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.

Using eROSITA-DE DR1 data, this study searches for dark matter decay signatures in the Large Magellanic Cloud, finding no evidence for sterile neutrinos or axion-like particles and consequently establishing new, stringent constraints on their mixing angles and couplings for masses below 5 keV.
This study employs QCD light-cone sum rules to calculate the magnetic dipole moments of hidden-charm pentaquarks using four distinct diquark-diquark-antiquark interpolating currents, demonstrating that these electromagnetic observables are highly sensitive to internal quark configurations and can effectively discriminate between compact and molecular structural models.
This paper evaluates a machine learning framework and a novel multipoint method for the ill-posed spectral reconstruction problem by comparing them against established techniques on mock data, then applying the most effective approaches to quenched lattice data to extract the electric conductivity in the presence of a non-zero external magnetic field.
This paper introduces a new "dark hyperCharge" symmetry where Standard Model fermions are chiral and anomaly cancellation is achieved via three dark singlet fermions, identifying the lightest of these as a viable dark matter candidate that interacts with the visible sector through a heavy boson while satisfying current collider and dark matter constraints.
This paper redefines the , , and parameters within the B-LSSM framework using the pinch technique to incorporate one-loop vertex corrections, demonstrating result convergence and showing how updated experimental data strongly constrain the model's parameter space.
This study constrains the parameter space of the General Next-to-Minimal Supersymmetric Standard Model (GNMSSM) by analyzing exotic decays of the 125 GeV Higgs boson into light scalar and pseudoscalar pairs under recent experimental constraints, revealing strict limits on singlet admixtures and identifying viable dark matter scenarios dominated by singlinos or higgsinos depending on whether the observed Higgs is the lightest or next-to-lightest CP-even state.
This paper demonstrates that simulation-based inference methods, particularly optimal-observable estimators and robust likelihood-ratio approaches, offer superior or comparable sensitivity to anomalous couplings in the channel compared to traditional histogram analyses, highlighting their potential to surpass current LHC constraints with Run 3 data.
This paper reviews the effective field theory analysis of intrinsic electric dipole moments (EDMs) as precision probes for new CP-odd physics, summarizing model-independent constraints on new physics at the 1 GeV scale and discussing implications for various Beyond the Standard Model scenarios.
This paper investigates the production of dark photons with masses between 0.4 and 3.5 GeV in negatively charged pion-proton collisions via inelastic pion bremsstrahlung and QCD Drell-Yan-like processes, estimating total cross sections and energy distributions relevant for the NA64h experiment and secondary pion beams in T2K, DUNE, and SHiP.
This study utilizes high-redshift ultraviolet galaxy luminosity functions from Hubble Space Telescope observations, combined with CMB and supernova data, to set stringent new constraints on dark matter-proton scattering cross sections for various velocity dependencies, demonstrating that lensed field data significantly improves limits on velocity-dependent interactions beyond existing bounds from Milky Way satellites and CMB anisotropies.
