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 perturbative conversion between the scheme and momentum-space subtraction schemes for semileptonic weak Hamiltonians, demonstrating how judicious choices of projectors eliminate artificial scale dependence caused by Ward identity violations and yield Wilson coefficients with significantly reduced renormalization scale sensitivity.
This paper proposes a minimal Majorana neutrino mass matrix texture realized via a hybrid Type-I and Type-II seesaw mechanism under an extended symmetry, which predicts equal Majorana phases, favors normal mass hierarchy, and forbids a vanishing reactor mixing angle within a partial tri-bimaximal mixing framework.
This paper presents updated heavy quark expansion predictions for the lifetimes of doubly charmed baryons, including next-to-leading order corrections and new terms, which confirm the expected lifetime hierarchy and yield a value for consistent with recent LHCb measurements.
This paper proposes using time modulation in weak nuclear decays as a probe for axion dark matter, deriving a theoretical framework to predict such variations, constraining axion parameters using existing Gran Sasso data on K and Cs, and suggesting a new electron capture measurement to extend sensitivity to higher axion masses.
This paper presents a combined analysis of differential Higgs boson production cross sections across four decay channels (, ZZ, WW, and ) using 138 fb of 13 TeV proton-proton collision data from the CMS detector, yielding a total production cross section consistent with Standard Model predictions and providing constraints on Higgs couplings within the -framework and effective field theory.
This paper demonstrates that quantum-inspired deep neural networks (QDNNs) offer superior predictive accuracy and tighter uncertainties compared to classical methods for extracting Compton form factors from JLab experimental data, establishing them as an efficient tool for future multidimensional studies of hadronic structure.
This paper demonstrates that while global multiplicity fluctuations introduce a constant vertical offset in the differential radial flow observable , only the shape of this distribution (or its derivative) contains genuine physical information about radial-flow dynamics, rendering its zero-crossing point physically insignificant.
This paper proposes an effective thermodynamic model for a black hole's interior composed of scalar quasiparticles, distinguishing between a dense core governed by a potential-energy functional and an inverse-temperature-like parameter, and a surrounding crust with finite kinetic temperature, to provide a unified framework for exploring singularity resolution and the thermodynamic origins of negative pressure and energy density.
This paper demonstrates that an ultralight scalar dark matter field coupling to neutrinos can significantly amplify the rate of lepton-flavour-violating muon-to-positron conversion in nuclei, thereby enabling upcoming experiments to establish stringent new constraints on neutrino-dark matter couplings that surpass current cosmological and terrestrial limits.
This work assesses the sensitivity of the upcoming gamma-ray missions COSI and AMEGO-X to sub-GeV fermionic dark matter in vector-scalar portal models and demonstrates that COSI can provide leading constraints on gamma-ray lines beyond CMB limits, while AMEGO-X can probe most of the viable parameter space for continuous gamma rays.
