Abstract

The anomalous < VVP > Green function and related form-factors (pi(0) -> gamma*gamma* and tau(-) -> X-nu(tau) vector form-factors, with X- = (KK pi)(-), phi(-)gamma, (phi V)(-)) are analyzed in this letter in the large-N-C limit. Within the single (vector and pseudoscalar) resonance approximation and the context of Resonance Chiral Theory, we show that all these observables overdetermine in a consistent way a unique set of compatible high-energy constraints for the resonance couplings. This result is in agreement with analogous relations found in the even intrinsic-parity sector of QCD like, e.g., F-V(2) = 3F(2). The antisymmetric tensor formalism is considered for the spin-one resonance fields. Finally, we have also worked out and provide here the relation between the two bases of odd intrinsic-parity Lagrangian operators commonly employed in the literature. (C) 2014 The Authors.

Bremsstrahlung in chiral medium: Anomalous magnetic contribution to the Bethe-Heitler formula

Jeremy Hansen, Kirill Tuchin

Summary: We investigate the photon bremsstrahlung in chiral media and analyze its resonance in the scattering amplitude. The resonance contribution is shown to be proportional to the magnetic moment of the target nucleus. We demonstrate that the presence of the chiral magnetic current enhances the anomalous contribution to the photon spectrum, leading to a distinct kneelike structure. The significance of the anomalous terms depends on the ratio of the chiral magnetic conductivity to the projectile fermion mass.

Constraints on late time violations of the equivalence principle in the dark sector

Cameron C. Thomas, Carsten van de Bruck

Summary: If dark energy is dynamical, it is expected to be coupled to matter, especially dark matter. Recent studies show that the coupling can become non-zero during the domination of dark energy, leading to violations of the equivalence principle in the dark sector. However, current observations and cosmological background evolution have weak constraints on these violations, and further studies in the non-linear regime are needed.

The case of equivalence of low and high energy constraints on Regge vector spectrum in AdS/QCD

S. S. Afonin, T. D. Solomko

Summary: The AdS/QCD models interpolate between low and high energy sectors of QCD. By calculating observable constants at low and high momenta independently and comparing them, researchers found an approximate coincidence that is surprising due to its natural property for conformal theories, which strong interactions are not conformal.

The anomalous Zb(b)over-bar couplings at the HERA and EIC

Bin Yan, Zhite Yu, C-P Yuan

Summary: This study introduces a novel method to address the discrepancy between precision measurements of bottom quark forward-backward asymmetry at LEP/SLC and the Standard Model prediction, proposing to probe the Zb (b) over bar coupling by measuring the single-spin asymmetry A(e)(b) of the polarized lepton cross section in neutral current DIS processes at HERA and EIC. The measurement of A(e)(b) at HERA and EIC can help break the degeneracy found in the anomalous Zb (b) over bar coupling, with potential implications for resolving the A(FB)(b) puzzle.

The high-density equation of state in heavy-ion collisions: constraints from proton flow

Jan Steinheimer, Anton Motornenko, Agnieszka Sorensen, Yasushi Nara, Volker Koch, Marcus Bleicher

Summary: In this study, a set of different equations of state were implemented in the molecular dynamics part of a non-equilibrium transport simulation to investigate the influence of density dependence on flow observables. The effects of high density phase transition and softening of equation of state on observables were explored. Comparing the results with experimental data, it was found that there is no strong phase transition below 4(n0) density.

Self-consistent O(4) model spectral functions from analytically continued functional renormalization group flows

Christopher Jung, Jan-Hendrik Otto, Ralf-Arno Tripolt, Lorenz von Smekal

Summary: This paper explores practicable ways for self-consistent calculations of spectral functions using analytically continued functional renormalization group (aFRG) flow equations. A particularly straightforward approach proposed is to include parametrizations of self-energies based on explicit analytic one-loop expressions. The results show the importance of self-consistency at all momenta in fixing the relation between particle masses and decay thresholds, offering a sound and practicable basis for calculations in more realistic effective theories.

Dispersive constraints on fermion masses

Hsiang-nan Li

Summary: We demonstrate that fermion masses in the Standard Model can be constrained by the dispersion relations obeyed by hadronic and semileptonic decay widths of a fictitious heavy quark Q with an arbitrary mass. We solve for a physical heavy quark decay width using known input from leading-order heavy quark expansion and a hadronic threshold for decay products. The predicted decay widths based on these masses agree with the data, suggesting that the parameters in the SM may not be free but arranged properly for internal dynamical consistency.

A thermodynamically consistent fractional visco-elasto-plastic model with memory-dependent damage for anomalous materials

Jorge Suzuki, Yongtao Zhou, Marta D'Elia, Mohsen Zayernouri

Summary: This study developed a thermodynamically consistent, fractional visco-elasto-plastic model coupled with damage, utilizing Scott-Blair rheological elements. Through fractional damage energy release rates and memory-dependent Lemaitre-type damage, the research highlighted the crucial role of fractional orders in visco-elasto-plasticity for damage evolution. The study also introduced a first-order semi-implicit fractional return-mapping algorithm and a finite-difference discretization method to reduce computational complexity.

Observational constraints and predictions of the interacting dark sector with field-fluid mapping

Joseph P. Johnson, Archana Sangwan, S. Shankaranarayanan

Summary: In this study, we investigate an interacting field theory model for the interaction between dark energy and dark matter. By comparing with cosmological data, we find that this interacting model is consistent with observations and obtain quantitative tools to distinguish between interacting and non-interacting dark energy scenarios.

Efficient multi-jet merging with the VINCIA sector shower

Helen Brooks, Christian T. Preuss

Summary: The extension of the CKKW-L multi-jet merging technique to sector showers in VINCIA allows for efficient multi-jet merging at high multiplicities while retaining accuracy. The method reduces the complexity of constructing shower histories to a linear scaling with the number of final-state particles, with overall event generation time and memory footprint remaining approximately constant. Comparison with conventional CKKW-L implementation in PYTHIA shows promising results for high merged multiplicities.

Lattice Constraints on the QCD Chiral Phase Transition at Finite Temperature and Baryon Density

Owe Philipsen

Summary: The article discusses the thermal restoration of chiral symmetry in QCD and the expected transition into a phase transition with a critical endpoint as baryon density increases. By simulating at zero and imaginary baryon chemical potential, the location of a potential non-analytic phase transition and its critical endpoint can be constrained. Studies show a possible critical point bound to μ(B) & GSIM; 3T.

Summary: Measurements of muon production from heavy-flavour hadron decays in Pb-Pb collisions at root s(NN) = 5.02 and 2.76 TeV using the ALICE detector at the LHC show an increased suppression of muon yields with increasing centrality for R-AA at root s(NN) = 5.02 TeV.

Electroweak effective theory and beyond Standard Model resonances

Juan Jose Sanz-Cillero, Antonio Pich, Ignasi Rosell

Summary: This study explores a non-linear realization of the electroweak symmetry-breaking pattern to construct a low-energy effective theory, which is later extended by heavy new-physics resonances. By imposing high-energy constraints from Weinberg sum-rules and form-factor asymptotic behavior, relations between resonance masses and low-energy effective couplings are obtained. These predictions are compared with current experimental data, leading to the inference of some resonance mass bounds.

Gravitational Coleman-Weinberg mechanism

Clara Alvarez-Luna, Sergio de la Calle-leal, Jose A. R. Cembranos, Juan Jose Sanz-Cillero

Summary: The Coleman-Weinberg mechanism is a method by which a scalar field without mass parameters acquires mass due to the anomalous nature of scale symmetry. It triggers spontaneous symmetry breaking and the appearance of a non-trivial vacuum through loop corrections.

Distinguishing electroweak EFTs with WLWL? n x h

Raquel Gomez-Ambrosio, Felipe J. Llanes-Estrada, Alexandre Salas-Bernardez, Juan J. Sanz-Cillero

Summary: The electroweak symmetry-breaking sector, which is an important and unknown part of the Standard Model, may be beyond the reach of current accelerator efforts. Therefore, effective field theory becomes a logical method to use, with Standard Model effective field theory becoming the standard. This article discusses the differences between Higgs effective field theory and Standard Model effective field theory, as well as correlations among corrections to the Higgs effective field theory coefficients that help determine the viability of Standard Model effective field theory.

Inhomogeneity of a rotating quark-gluon plasma from holography

Nelson R. F. Braga, Octavio C. Junqueira

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Constrain the time variation of the gravitational constant via the propagation of gravitational waves

Bing Sun, Jiachen An, Zhoujian Cao

Summary: This paper investigates the effect of gravitational constant variation on the propagation of gravitational waves. By employing two analytical methods, the study finds that variations in the gravitational constant result in amplitude and phase corrections for gravitational waves, and the time variation of the gravitational constant can be constrained through the propagation of gravitational waves.

Quantum tunneling from Schwarzschild black hole in non-commutative gauge theory of gravity

Abdellah Touati, Zaim Slimane

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Compact stars: To cross or go around? That is the question

Shahar Hod

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
