Abstract

The distribution of the gluon action density in mesonic systems is investigated at finite temperature. The simulations are performed in quenched QCD for two temperatures below the deconfinement phase. Unlike the gluonic profiles displayed at T = 0, the action-density isosurfaces display a prolate-spheroid-like shape. The curved width profile of the flux tube is found to be consistent with the prediction of the free bosonic string model at large distances.

Constructing static quark-antiquark creation operators from Laplacian eigenmodes

Roman Hoellwieser, Francesco Knechtli, Tomasz Korzec, Michael Peardon, Juan Andres Urrea-Nino

Summary: We investigate static quark-antiquark operators based on trial states formed from eigenvectors of the covariant three-dimensional lattice Laplace operator. We test the method by computing the static quark-antiquark potential and comparing results to standard Wilson loop measurements. The new method is efficient not only for on-axis, but also for many off-axis quark-antiquark separations when a fine spatial resolution is required.

Degenerate fermionic matter at N3LO: Quantum electrodynamics

Tyler Gorda, Aleksi Kurkela, Juuso Oesterman, Risto Paatelainen, Saga Saeppi, Philipp Schicho, Kaapo Seppaenen, Aleksi Vuorinen

Summary: We have calculated the pressure of a cold and dense electron gas to a nearly complete N3LO in the fine-structure constant alpha e, using a new result for the two-loop photon self-energy. Our result includes all infrared-sensitive contributions to the pressure at this order, and only leaves a single undetermined coefficient associated with the contributions of unresummed hard momenta. We have also demonstrated the complete cancellation of infrared divergences according to the effective-field-theory paradigm by determining part of the hard contributions at this order.

Seunghye Lee, Minhee Seo, Sun-Myung Kim, Thuc P. Vo, Jaehong Lee

Summary: This study presents a parametric study for a two-way beam string structure to provide optimal design parameters. Numerical examples validate the effects of different parameters on the structure, including the number of struts, deflections and stresses, as well as cable curvatures. The study also investigates the stress sharing ratio of the beam's top/bottom and the sagging cable under positive and negative pressure.

Igor I. Strakovsky, William J. Briscoe, Lubomir Pentchev, Axel Schmidt

Summary: High-accuracy meson photoproduction data from EIC and EicC experiments are used to measure the near-threshold total cross section of the reaction gamma p -> (sic)p, allowing extraction of the absolute value of the (sic)p-scattering length. Comparative analysis is conducted with recently determined scattering lengths for omega p, phi p, and J/psi p using experimental data from A2, CLAS, and GlueX to evaluate the role of the young vector-meson effect.

Summary: The possibility of quark matter existence in neutron stars has been a long-standing question. By considering a crossover equation of state, it is found that neutron stars up to about 2.2 solar masses may be supported, with 1% to 10% of pressure contributed by quark matter in the central core of the highest mass stars.

Nuclear matter at finite temperature and static properties of proto-neutron star

Debashree Sen

Summary: Using an effective chiral model, this study investigates the finite temperature properties of nuclear matter, focusing on the phase transition possibilities of symmetric nuclear matter and examining properties of asymmetric nuclear matter. The research also extends to obtaining the equation of state for beta stable nuclear matter at finite temperature, and computes various static proto-neutron star properties for different temperatures. The results are found to be consistent with observational constraints from massive pulsars and satisfy constraints on surface redshift from specific sources.

Effects of the CPT-even and Lorentz violation on the Bhabha scattering at finite temperature

P. R. A. Souza, A. F. Santos, Faqir C. Khanna

Summary: This paper considers a Lorentz-violating CPT-even non-minimal coupling term, leading to a new interaction term between fermions and photons. The differential cross-section for Bhabha scattering at finite temperature is calculated, with temperature effects introduced using Thermo-Field Dynamics (TFD) formalism. It is shown that the differential cross-section is altered by both Lorentz violation and finite temperature.

Summary: The paper examines the sensitivity of the parity-violating electron scattering asymmetry to the properties of a dark photon, and explores its impact on both elastic and deep-inelastic scattering. With recent advancements in experimental capabilities, there is potential for discovering new physics through PVES, as well as a potential for altering our understanding of atomic nuclei, neutron stars, and parton distribution functions through the existence of a dark photon.

Probing EWPT in 2HDM with future lepton colliders

Wei Su, Anthony. G. G. Williams, Mengchao Zhang

Summary: By extending the Higgs sector in the Standard Model with extra scalars, the electroweak phase transition can be made first order. In this study, we focus on the strong first-order electroweak phase transition in the Type-II two Higgs doublet models. Through a parameter space scan, we find upper limits on the masses of the heavy Higgs, which are less than 1TeV. High-temperature expansion and Higgs vacuum uplifting are used for analytical understanding of the results. We also investigate the possibility of probing the strong first-order electroweak phase transition at the one-loop level through precision measurements at future Higgs and Z factories.

Static quark potential from center vortices in the presence of dynamical fermions

James C. Biddle, Waseem Kamlehe, Derek B. Leinweber

Summary: This study identifies center vortices for the first time on SU(3) lattice ensembles with dynamical fermions. By using a variational method, the static quark potential is calculated on different field configurations, including untouched, vortex-removed, and vortex-only fields. The impact of dynamical fermions on the center-vortex vacuum is explored by studying two dynamical ensembles and one pure gauge ensemble. Novel modifications to the standard Coulomb term are introduced to improve the accuracy of the fitted string tension on the original ensembles. The results show that the vortex-only fields on both dynamical ensembles can fully reproduce the respective untouched string tensions.

Perturbative width of open rigid strings

A. S. Bakry, M. A. Deliyergiyev, A. A. Galal, M. N. Khalil

Summary: In this paper, we present a perturbative calculation of the energy profile width of rigid strings up to two loops in D dimensions. We use the perturbative expansion of the extrinsic curvature term to study the rigidity/smoothness of the string in the Polyakov-Kleinert action. By deriving the mean-square width of the string field for open strings with the Dirichlet boundary condition, we compare the broadening of the smooth Polyakov-Kleinert string to lattice Monte Carlo data of the QCD flux tube, finding a good match at intermediate and large color source separation.

Quark-gluon vertex from Nf=2 lattice QCD

Ayse Kizilersu, Orlando Oliveira, Paulo J. Silva, Jon-Ivar Skullerud, Andre Sternbeck

Summary: The study shows that the quark-gluon vertex has significant infrared strength in the limit of vanishing gluon momentum, with the form factors lambda(1) and lambda(3) being significantly enhanced in the infrared compared to the quenched case. The enhancements are orders of magnitude larger than predicted by one-loop perturbation theory, with only a weak dependence on lattice spacing and quark mass.

Curtis D. Abell, Derek B. Leinweber, Anthony W. Thomas, Jia-Jun Wu

Summary: The process of renormalization in nonperturbative Hamiltonian effective field theory (HEFT) is examined in the Delta-resonance scattering channel. HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy eigenstates in lattice QCD, and examines the sensitivity of the finite-volume spectrum and state composition on the regulator.
