Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

This paper calculates the ratio of low-mass -boson to Standard Model -boson contributions to parity nonconservation in hydrogen and deuterium, demonstrating that these light atoms offer a theoretically clean and highly sensitive environment for detecting hypothetical new vector bosons due to the rapid increase in the signal relative to the Standard Model background as nuclear charge decreases.
This paper demonstrates that requiring UV completeness in a specific class of scalar-tensor gravity models restricts their infrared parameters to a narrow region, thereby ruling out a portion of the parameter space currently accessible to fifth-force experiments and offering a direct path to falsify these theories.
This paper reports that the 2023 summation model for reactor antineutrino fluxes revives the Reactor Antineutrino Anomaly at a significance level, creating a tension with gallium anomaly results and other neutrino data, which is reduced to when gallium systematic uncertainties are enlarged.
This paper presents a unified taxonomy and structured overview of uncertainty quantification in machine learning for physics, clarifying interpretations across statistical frameworks and outlining principled validation tools to ensure reliable probabilistic statements for scientific discovery.
This paper develops a light-front Hamiltonian formalism using the time-dependent Basis Light-Front Quantization framework to simulate the real-time quantum evolution of a high-energy quark in the Glasma, successfully computing transverse momentum broadening and the jet quenching parameter while demonstrating consistency with classical estimates and providing a foundation for future systematic improvements.
This paper investigates several simple asymptotically-free chiral gauge theories to reveal surprisingly rich infrared effective structures, RG flows, and light spectra by applying recent developments in generalized symmetries and anomaly matching alongside established knowledge of vectorlike theories.
This paper demonstrates through numerical simulations that in spatially inhomogeneous core-collapse supernova environments, the dynamic competition between Fast and Collisional Flavor Instabilities and collisional damping leads to diverse intermediate evolutionary pathways, yet consistently results in a flavor-equilibrated asymptotic state, thereby challenging the widely accepted collisionless picture of Fast Flavor Instability.
This paper investigates how implementing a temperature-dependent thermal cutoff to ensure renormalization group consistency in RGNJL and RGPNJL models resolves causality violations, improves convergence to the Stefan-Boltzmann limit, and enhances the description of net-baryon number fluctuations compared to lattice QCD data, while revealing complex sensitivities in the PNJL framework at high baryon densities.
This paper demonstrates that vector boson fusion processes at the LHC can distinguish between Higgs portal and neutralino dark matter scenarios with over confidence by exploiting characteristic differences in jet transverse momentum and kinematic variables like and .
This paper explains the anomalously suppressed decay of within a conventional charmonium framework by demonstrating that node-induced cancellations in the relativistic decay amplitude significantly reduce the width while leaving other open-charm channels largely unaffected.
