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 demonstrates that a uniform wounded parton Glauber model, assuming four partons per nucleon and incorporating negative binomial fluctuations, successfully describes charged particle multiplicity distributions across O+O, Ne+Ne, Xe+Xe, and Pb+Pb collisions at TeV using a single set of parameters for centralities up to approximately 1%.
This paper demonstrates that the exact family-separated seesaw ansatz enforces a specific mathematical structure where all standard nonresonant one-loop decay asymmetries vanish, thereby invalidating the proposed correlation between low-energy CP violation and these decay asymmetries while correcting associated mass reconstruction formulas and clarifying implications for neutrinoless double-beta decay.
This paper employs QCD sum rules to systematically calculate the form factors for the weak transition and uses them to predict various physical observables, including partial widths, branching fractions, and polarization parameters, for the corresponding semileptonic decays to aid future experimental studies of doubly heavy baryons.
This paper derives scattering amplitudes based on geometric scaling to accurately reproduce most parameter data, demonstrating that a slight modification of the total cross-section to include the Odderon is necessary to accommodate the 13 TeV TOTEM and ATLAS measurements.
This paper investigates how classical stochastic fluctuations in a background electric field affect a self-interacting charged scalar field theory, utilizing the replica trick to derive an effective current-current interaction and subsequently determining the theory's renormalization group flows across weak and ultra-strong field regimes.
This paper demonstrates that, unlike in classical mechanics where constraints eliminate unphysical center-of-mass variables, all canonical degrees of freedom in a quantum -particle system are physical because non-relational variables cannot be removed without losing information, leading to generalized uncertainty relations that define the quantum reference frame itself.
This study demonstrates that Higgs-portal fermionic dark matter significantly softens the neutron star equation of state, systematically reducing maximum mass, radii, and tidal deformability, with the latter serving as a highly sensitive discriminator capable of distinguishing dark matter content from nucleonic uncertainties at the $7.5$- level.
This paper investigates a cascade dark matter decay scenario where fermionic dark matter decays into a neutrino and a light mediator that subsequently produces photons, demonstrating that while gamma-ray constraints typically dominate, neutrino line searches offer competitive or leading sensitivity when the mediator's finite decay length significantly suppresses the photon signal.
This paper employs QCD light-cone sum rules with light-cone harmonic oscillator models to calculate transition form factors for decays, subsequently predicting branching fractions, testing lepton flavor universality via the ratio , and extracting the CKM matrix element .
This paper proposes a coupled-channel potential model incorporating a Kapitza-inspired term to describe the X(3872) as a hybrid state with both molecular and compact tetraquark components, successfully reproducing its experimental mass and offering a mechanism for threshold tuning.
