Space-like Sachs electric and magnetic form factors of the baryons in the asymmetric nuclear medium

This paper investigates the space-like Sachs electric and magnetic form factors of baryons in asymmetric nuclear matter at finite temperature using a vector meson dominance model coupled with QCD sum rules and a chiral SU(3) quark mean field framework, while also calculating in-medium charge radii and comparing the results with existing phenomenological models, lattice simulations, and experimental data.

Testing the Shock-cooling Emission Model from Star-Disk Collisions for Quasiperiodic Eruptions

By systematically analyzing peak luminosities, durations, and radiation temperatures of quasiperiodic eruptions, this study demonstrates that the shock-cooling emission model from star-disk collisions fails to explain the majority of observed sources due to inconsistent stellar radius constraints and significantly underestimated radiation temperatures.

Bubble wall velocity from Kadanoff-Baym equations: fluid dynamics and microscopic interactions

This paper establishes a first-principles framework based on non-local Kadanoff-Baym equations that unifies macroscopic fluid dynamics and microscopic particle interactions to systematically determine bubble wall velocity, revealing a linear friction force from 2→22\rightarrow 2 scattering that prevents runaway bubbles in the ballistic regime.

Application of the 3-Loop FlexibleEFTHiggs Method to the MSSM and the NMSSM

This paper presents an extensive analysis of the light CP-even Higgs boson pole mass in the MSSM and NMSSM using the newly implemented 3-loop FlexibleEFTHiggs hybrid calculation in FlexibleSUSY, focusing on its robustness in scenarios with highly non-degenerate SUSY spectra and providing an improved, uncertainty-assessed Higgs mass prediction for the NMSSM.

Poles from the conserved kinetic equation: The emerging gradient structure and causality riddle of relativistic hydrodynamics

This paper demonstrates that by employing a collision kernel conserving energy-momentum and particle current, the poles of the relativistic kinetic equation yield a dispersion relation with a systematic gradient structure where spatial and temporal gradients appear in unison, thereby ensuring causality in truncated hydrodynamic theories.

Pion scattering in finite volume within the Inverse Amplitude Method

This paper presents a comprehensive finite-volume calculation of pion-pion scattering within Chiral Perturbation Theory and the Inverse Amplitude Method that incorporates discretization effects across all scattering channels and group representations, revealing significant corrections for small volumes (mπL≲2m_\pi L \lesssim 2) that improve the accuracy of energy level and phase-shift determinations compared to previous analyses.
