Summary: Solutions to the mu problem in supersymmetry based on the Kim-Nilles mechanism naturally include a DFSZ axion with enhanced couplings, where anomaly-free discrete symmetries play a crucial role in protecting the Peccei-Quinn symmetry. These models require at least one pair of strongly interacting vectorlike multiplets at an intermediate scale to be free of the domain wall problem, making them promising for proposed axion searches.

Summary: The gauged U(1)(L mu-L tau) model is studied as a potential explanation for the muon g-2 anomaly. The results show that the model allows for a large mass for the Z' particle with a maximal off-diagonal mixing. The processes of t-channel tau(-)tau(+) pair production and doubly same sign mu(+/-)mu(+/-) + tau(+/-)tau(+/-) pairs production are analyzed in detail, and their distinguishability from the standard model predictions is discussed.

Summary: In this study, a scotogenic neutrino model with a gauged lepton number symmetry U(1)(mu-tau) is employed to investigate the muon anomalous magnetic moment (muon g - 2), revealing that the dominant contribution to muon g - 2 comes from the Yukawa sector rather than an additional gauge sector. The numerical Delta chi(2) analysis shows that the model favors the normal hierarchy and presents a benchmark point that satisfies the muon g - 2 at the best fit value 25.1 x10(-10).

Summary: We investigate an economical explanation for the (g - 2)mu anomaly with a neutral vector boson from a spontaneously broken U(1)(x) gauge symmetry. The Standard Model fermion content is minimally extended by 3 right-handed neutrinos. Using a battery of complementary constraints, we perform a thorough investigation of the renormalizable, quark flavor-universal, vector-like U(1)(x) models, allowing for arbitrary kinetic mixing.

Summary: In this work, the hard-wall AdS/QCD model proposed by Katz and Schwartz is employed to compute the hadronic light-by-light scattering contributions of pseudoscalar and axial-vector mesons to the anomalous magnetic moment of the muon. By introducing a gluon condensate as an additional tunable parameter, accurate fits for the masses and decay rates of eta and eta0 to photons are obtained, leading to mu contributions in agreement with the Standard Model result. The predictions for the less understood axial-vector contributions are updated in this study.

Summary: The recent measurement of the muon anomalous magnetic moment has confirmed tension with the Standard Model prediction, motivating the search for new physics. Among various particle physics models, the gauged U(1)(Lμ-Lτ) stands out for its simplicity. Future experiments, such as muon fixed target experiments and neutrino-nucleus scattering experiments, will provide crucial information on the nature of new physics behind the muon anomalous magnetic moment.

Summary: In this article, we examine the properties of the Pesaran CD test when applied to residuals from panel data models with many estimated parameters. We find that the CD test statistic diverges as the time dimension of the sample grows due to the presence of period-specific parameters, even if cross-section dependence is correctly considered. We propose a weighted CD test statistic to restore standard normal inference under the null hypothesis.

Summary: This paper presents an extension of Mandel's problem to consider dynamic response of a porous, fluid-saturated, and viscoelastic specimen with similar geometry and boundary conditions. The results show that the dynamic solution provides more accurate results compared to the quasi-static approximation, even at frequencies lower than the specimen's first natural frequency.

Summary: We propose a new U(1)(mu-tau) gauged model that can explain recent flavor anomalies and include a scalar dark matter candidate. In our model, the b -> s mu(+)mu(-) anomalies can be explained by loop-induced interactions among the standard model, exotic quarks, and Z' gauge boson. Our numerical analysis shows that the allowed region of our model is narrow and can be tested soon by searching for specific particle decay processes at the LHC.

Summary: By utilizing Goldstino properties, it has been shown that in generic grand unified theories, the At problem does not exist, and the shifts of heavy fields generating At and BAt terms are induced universally by supersymmetry breaking, regardless of the scale of grand unification. This mechanism works irrespective of whether doublet-triplet splitting is achieved through fine-tuning or not.

Summary: The issue of fisheries waste has been increasing globally due to various factors. The utilization of these waste materials as raw materials has been proven to be effective in addressing the crisis faced by the oceans and improving marine resource management. However, the implementation of valorization strategies at the industrial level has been slow, particularly in the case of chitosan extracted from shellfish waste. To overcome this, a sustainable and circular economy approach should be adopted for chitosan valorization.

Summary: The rotation of the QCD axion field, aided by B-L violation from supersymmetric R-parity violating couplings, can convert into the baryon asymmetry of the Universe. This scenario, with constraints from grand unified theories and various mechanisms, can be studied through nucleosynthesis, proton decay, and axion dark matter.

Summary: This study introduces a new class of beyond the Standard Model states called Loryons, which are characterized by their non-decoupling nature. The study focuses on the parameter space and constraints of Loryons, showing that most fermionic candidates are ruled out while the scalar Loryon parameter space remains open for discovery.

Summary: We present a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies and luminosities. The advantages of this collider over proposed alternatives are highlighted, and we demonstrate how the characteristics of muons and the surrounding electroweak radiation can blur the distinction between energy and precision in the search for new physics. Our findings have implications for electroweak symmetry breaking, dark matter, and the naturalness of the weak scale, and we establish connections with complementary experiments probing new physics effects using electric dipole moments, flavor violation, and gravitational waves.

Summary: Effective Field Theory (EFT) is a tool to compute observables in particle physics. When searching for EFT effects at colliders, it is important to consider self-consistency. We propose a new approach that incorporates parton distribution functions into the analysis, and provide evidence for the validity of EFT predictions in certain parameter spaces.

Summary: Hamiltonian truncation is a method for calculating observables in quantum field theory, where the effective Hamiltonian is defined by integrating out high-energy states. The method is systematically treated using effective field theory and corrections are computed as an expansion in powers of 1/Emax. The corrections satisfy the property of separation of scales, as demonstrated in 2D lambda phi 4 theory.

Summary: Complex scalar fields that rotate in the early universe may explain the observed perturbations in the universe and could exhibit detectable non-Gaussianity in future observations. This rotation can also explain the baryon asymmetry of the universe without producing excessive isocurvature perturbations.

Summary: High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles beyond the acceptance of existing experiments. The proposed Forward Physics Facility (FPF) will host experiments to probe standard model processes and search for physics beyond the standard model (BSM). FPF experiments will explore BSM physics through searches for new particle scattering or decay signatures and deviations from SM expectations in a low-background environment.

Summary: The tilting of the Milky Way's stellar disc can be greatly influenced by infalling satellite galaxies and their tidal debris. This study uses N-body simulations to investigate the dynamics of disc tilting in a Milky Way-like host galaxy, considering satellite virial mass, initial position, and orbit as variables. The results suggest that the Galactic disc may still be tilting due to recent mergers, such as Gaia-Sausage-Enceladus, which has important implications for terrestrial direct detection experiments.

Summary: Scattering amplitudes in quantum field theory are geometrically invariant under field redefinitions and can be expressed in terms of Riemannian curvature tensors. A generalized geometric framework is presented to extend the manifest covariance of amplitudes to all allowed field redefinitions. The amplitudes exhibit a recursive relation that resembles the application of covariant derivatives, indicating a notion of on-shell covariance at tree-level.

Summary: Non-trivial inflaton self-interactions can generate primordial nonGaussianity, which can be measured in cosmic surveys. We calculate the non-Gaussian corrections to Stochastic Inflation and derive the probability distribution for scalar fluctuations. We find that the phase transition to slow-roll eternal inflation is often incalculable and is sensitive to the non-Gaussian tail of the distribution of scalar fluctuations.

Summary: Fluctuations in cosmology are crucial and can be coarse grained with Gaussian distribution or dominated by rare fluctuations. The large deviation principle is proposed to diagnose when the fundamental description is necessary. The Fokker-Planck equation governing stochastic inflation shows central limit-type behavior for typical fluctuations, but instantonlike saddle points accompanied by a new energy scale determine fluctuations in the regime of the large deviation principle.

Summary: This study shows that weak-scale secluded sector dark matter can reproduce the observed dark matter relic density through thermal freeze-out in that sector. In the case of supersymmetry, three portals connect the visible sector to the secluded sector - a gauge portal, a Higgs portal, and a gaugino portal. The results suggest that symmetries in the secluded sector can stabilize dark matter, making R-parity unnecessary.
