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 the framework of modern generative networks used in physics for fast surrogates and density estimation, while addressing the challenges in quantifying their accuracy, precision, and statistical power.
This paper demonstrates that the residual power spectrum of multiply-imaged galaxies in strong cluster lenses, as observed by JWST, can statistically distinguish wave-like dark matter from standard cold dark matter by quantifying sub-galactic density fluctuations across the scale.
This paper establishes that local baryon conservation within a canonical statistical hadronization framework can drive higher-order net-proton cumulant ratios to small or negative values in restricted rapidity acceptances, necessitating careful accounting of this baseline to avoid misinterpreting upcoming LHC measurements as signals of chiral criticality.
This paper investigates the projected sensitivity of the FCC-ee at GeV with 5 ab luminosity to Lepton Flavor Violating Higgs decays into , , and final states, establishing 95% CL upper limits on their branching ratios and demonstrating that FCC-ee constraints surpass low-energy searches for the and channels, while remaining less stringent for the channel.
This paper reviews recent interferometric schemes that utilize geometric phase shifts in ordinary fermion systems to detect interactions with hidden-sector degrees of freedom, such as axion-like particles and mirror-matter candidates, as a means of probing physics beyond the Standard Model.
This paper presents a complete next-to-leading-order calculation of QED radiative corrections to elastic electron-proton and muon-proton scattering, with a specific focus on the structure-dependent two-photon-exchange diagrams to address discrepancies like the proton radius puzzle and test lepton universality.
This paper presents the first non-perturbative lattice determination of bubble nucleation rates seeded by topological defects in a cubic anisotropy model, demonstrating excellent agreement with semi-classical predictions that include fluctuation determinants away from spherical symmetry.
This paper utilizes the isospectral family of the softwall AdS/QCD model to demonstrate that the ground-state electromagnetic decay constant is a key scale controlling the melting temperature of the meson, yielding a holographic prediction of MeV that aligns with experimental constraints.
Using N-body simulations and a semi-analytical model, this study demonstrates that gravothermal collapse in self-interacting dark matter halos remains robust against baryonic feedback, with high-concentration halos collapsing despite strong feedback and median-concentration halos resuming collapse after feedback ceases, thereby supporting the identification of dense compact perturbers in strong-lensing observations as core-collapsed SIDM halos.
This paper classifies new physics models featuring narrow boson resonances that could induce significant di-lepton non-universality in the bottomonium mass region at the LHC through enhanced di-tau decays, proposing that simultaneous measurements of di-electron, di-muon, and di-tau spectra could reveal these new states or non-Standard Model bottomonium decays.
