This paper demonstrates that suitable quartic couplings in the Pati-Salam model can prevent symmetry restoration at high temperatures, thereby avoiding the thermal production of 't Hooft-Polyakov monopoles and removing constraints on the symmetry breaking scale.
This paper presents an exact analytical evaluation of the two-photon exchange correction to elastic lepton-proton scattering at low energies using heavy-baryon chiral perturbation theory up to NNLO, revealing non-vanishing proton structure effects and demonstrating good perturbative convergence for the kinematic regime relevant to the MUSE experiment.
This paper utilizes QCD light-cone sum rules with high-twist and next-to-leading-order corrections to reanalyze transition form factors, confirming chiral enhancement effects and extracting optimal - mixing parameters that are strongly favored by recent BESIII experimental data.
This paper evaluates the sensitivity of future and colliders to top quark Flavor Changing Neutral Currents within Randall-Sundrum models, incorporating current and projected HL-LHC limits to determine that while the HL-LHC may reach branching ratios of , high-energy lepton colliders offer the potential to probe even smaller coupling strengths.
By combining Machine Learning techniques with the inclusion of crucial kite and Barr-Zee diagrams, this study demonstrates that large CP-odd couplings for the 125 GeV Higgs boson in Type-II and Flipped C2HDM scenarios can be resurrected through precise cancellations, shifting the primary constraints from electron electric dipole moment limits to LHC precision measurements.
This paper introduces the Monte Carlo event generators BHLUMI and BHWIDE for simulating small and large angle Bhabha scattering, respectively, and outlines potential improvements to meet the precision requirements of future electron-positron colliders.
Numerical simulations of ultra-light dark matter halos in dwarf galaxies reveal that dynamical evolution and soliton core effects disfavor particle masses between eV and eV based on observational data from Fornax, Carina, and Leo II, while noting that lower masses may be constrained by tidal stripping and the omission of stellar self-gravity.
This paper proposes and evaluates strategies, including cut-based, supervised, and weakly supervised anomaly searches using the CATHODE method, to detect TeV-scale resonances connected to a dark QCD sector via low-transverse-momentum tracks in LHC data, specifically benchmarking a quirk model with microscopic string lengths.
This paper establishes that in the large limit of semi-holographic gauge theories, the unique global thermal equilibrium state—characterized by a single physical temperature and maximum entropy—is the inevitable relaxation outcome for typical non-equilibrium states with sufficiently high energy density, despite the system's capacity to sustain a pseudo-equilibrium with distinct temperatures between its perturbative and non-perturbative subsectors.
This paper employs the symmetry-improved Cornwall-Jackiw-Tomboulis formalism within a three-flavor linear sigma model to resolve artificial chiral symmetry breaking issues in the conventional approach, thereby mapping the Columbia plot and identifying a first-order phase transition with a tricritical point at a specific strange quark mass and a critical pion mass of approximately 52.4 MeV in the three-flavor symmetric limit.
