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 proposes a method to distinguish between vector and scalar dark sector mediators by analyzing the angular distributions of their decay products, demonstrating that experiments like DUNE, SHiP, and FASER2 can determine the mediator's spin in significant regions of unconstrained parameter space.
This paper presents a comprehensive analysis of charged parent freeze-in dark matter models in low-reheating-temperature scenarios, demonstrating that Boltzmann suppression enables stronger couplings to the Standard Model while revealing critical dependencies on mass scales and the necessity of tracking non-equilibrium mediator dynamics to accurately predict relic abundance and constrain the parameter space via LHC and lepton-flavor-violation searches.
This paper investigates the sensitivity of exclusive dilepton production in proton-proton collisions to the proton radius, finding that while current ATLAS and CMS data within a dipole form factor model suggest an effective radius of fm, this result is not yet sufficient to definitively resolve the proton radius puzzle.
This paper proposes a supersymmetric framework where non-thermal dark matter production via a singlet mediator in smooth hybrid inflation imposes tight constraints on the inflationary parameter space, predicting a scalar spectral index of and inducing observable modifications to primordial gravitational waves.
This paper proposes a novel search for charged lepton flavor violation via muon-to-tau conversion using cosmic-ray muon samples in neutrino telescopes like IceCube, demonstrating their potential as a powerful complementary probe to low-energy experiments and colliders for constraining new physics models.
This paper constrains the mass of microscopic black holes produced at the LHC with TeV within the ADD model, demonstrating that higher energy loss during formation (parameterized by ) and varying numbers of extra dimensions significantly reduce the exclusion limits on the black hole mass for different reduced Planck scales.
This paper proposes a theoretically grounded method for extracting charmonium branching fractions from radiative decays that resolves tensions between experimental data and theoretical predictions by eliminating the need for empirical damping functions in photon line shape analysis.
This paper investigates the production of heavy neutral leptons at multi-TeV muon colliders via new vector boson fusion processes involving a boson and heavy Higgs, demonstrating that these mechanisms offer enhanced, mixing-angle-independent pathways to probe lepton number violation compared to standard model channels.
This paper constructs and analyzes static monopole and monopole-critical-bubble configurations in the Coleman-Weinberg model to demonstrate how radiative symmetry breaking leads to metastable monopoles that lose stability via a saddle-point transition at a critical rescaled scalar mass of .
This paper presents the first systematic scan of two-flavon Froggatt-Nielsen models using the Non-dominated Sorting Genetic Algorithm III to efficiently identify over 100,000 phenomenologically viable configurations that naturally explain CP violation, fermion masses, and mixing patterns across both quark and lepton sectors.
