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 introduces a framework utilizing linear response and influence functions to quantify how experimental data constrains non-perturbative functions in global QCD analyses, thereby providing a transparent method to diagnose information flow and sensitivity in these complex inverse problems.
This paper presents the first calculation of next-to-next-to-leading order (NNLO) QCD radiative corrections for deeply virtual pion production, demonstrating that these two-loop corrections substantially improve the agreement between perturbative QCD predictions and experimental data from JLab while also refining theoretical descriptions of transverse single-spin asymmetries for future facilities like the EIC and EicC.
This paper demonstrates that the zero-mass limit of the partition function for covariant locally localized gravity on a Karch-Randall braneworld yields a theory containing a massless graviton and a decoupled massive vector, rather than the standard Randall-Sundrum II model, by deriving a fully covariant description to compute the one-loop partition function.
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.
