This paper introduces Systematic Analytic Regularization (SAR), a novel scheme that regularizes quantum field theories by analytically continuing the power of the kinetic operator at the action level to ensure formal finiteness, and demonstrates its self-consistent application to and Yukawa theories at next-to-leading order.
This paper proves that under fundamental physical principles, any quantum system coupled to a scale-invariant environment decoheres uniquely as an "unparticle bath" characterized by a single scaling dimension, a framework validated by experimental data and unified across diverse physical regimes from condensed matter to cosmology.
This paper presents a comprehensive derivation of the rovibrational spectrum for hydrogen and antihydrogen molecular ions within the non-minimal Standard-Model Extension, demonstrating how high-precision spectroscopy of these systems can test Lorentz and CPT symmetry with sensitivities up to by analyzing quantum number dependencies and temporal variations.
This paper investigates the sensitivity of the DUNE near detector's liquid argon cube to sub-GeV inelastic dark matter within a UV-complete framework featuring a dark Higgs mechanism, demonstrating its unique ability to probe parameter space consistent with the observed relic abundance, particularly in regions where traditional decay-based searches are ineffective.
This chapter explains the origins and significance of the proton radius puzzle, which arose from a discrepancy between muonic and electronic hydrogen measurements suggesting a potential violation of lepton universality, and presents recent experimental results that have successfully resolved the issue.
This paper presents a theoretical study of charged current -induced deep inelastic scattering on at DUNE-relevant energies, utilizing a microscopic framework with nuclear medium effects and NNLO QCD corrections to compute nuclear structure functions and differential cross sections.
This study employs Bayesian inference to demonstrate that while jet quenching constraints across collision centrality are compatible, variations in beam energy and observable classes reveal distinct aspects of jet-medium interactions that limit predictive universality, motivating the use of leading-hadron-selected observables to bridge these gaps.
This paper investigates rare dileptonic decays of , , and baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.
Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.
This brief review outlines the main theoretical frameworks for neutrino masses, with a specific focus on Majorana scenarios involving the spontaneous breaking of global lepton number and the phenomenological implications of the resulting massless Goldstone boson, the majoron.
