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 derives a closed formula for computing static post-Newtonian corrections to two-body gravitational dynamics at any odd order using a correlation function framework and symmetry, which is applied to successfully calculate the seventh-order potential and confirm its agreement with diagrammatic factorization theorem results.
This paper presents a theoretical framework comparing electromagnetic radiation signatures from scalar fields in modified gravity with those of axion-like particles, demonstrating how distinct parity couplings and resonance effects can produce observable differences to aid in distinguishing between these models.
This paper proposes a novel extension of Light-Front Holographic QCD that incorporates a flavor-dependent dynamical spin-orbit potential to accurately predict mass splittings and Regge trajectories for both light and heavy baryons, thereby bridging the gap between light and heavy quark dynamics in baryon spectroscopy.
This paper demonstrates that in dynamical Chern-Simons gravity, the parity-odd trispectrum of curvature perturbations is not an independent observable but can be fully expressed as a rational, factorized "double copy" of the parity-odd graviton power spectrum and the mixed inflaton-graviton bispectrum.
This study employs QCD sum rules with color-singlet currents and dimension-12 vacuum condensates to predict the masses of charm-strange and bottom-strange hadronic molecules, finding that the predicted masses for , , and states align well with experimental data for , , and , while the state is predicted to be a bound molecular state below its threshold.
This paper utilizes the energy-dependent hotspot model with various nuclear shape prescriptions to predict cross sections for coherent and incoherent diffractive vector meson ( and J/) photo-production in oxygen-oxygen and neon-neon ultraperipheral collisions at the LHC, demonstrating that simultaneous measurements of these processes can constrain nuclear models and probe the gluon-saturation regime.
This paper investigates the moat regime in dense QCD matter using a renormalized two-flavor quark-meson model, demonstrating that the regime's extent critically depends on quark-meson interactions and that a specific renormalization scheme is essential for obtaining reliable, consistent results.
This paper investigates the phenomenology of pseudo-Nambu-Goldstone bosons and light gauge bosons arising from the subgroup of a flavor model, demonstrating that their unsuppressed flavor-violating couplings allow low-energy flavor experiments to probe symmetry breaking scales up to GeV, surpassing current astrophysical limits.
This paper systematically investigates contact contributions to baryon number violating nucleon decays into three leptons by constructing a complete basis of dimension-9 operators in low-energy effective field theory, matching them to chiral perturbation theory to calculate decay widths, and deriving stringent constraints from experimental data while illustrating connections to ultraviolet-complete models.
This paper proposes that the Electron-Ion Collider (EIC) can significantly enhance sensitivity to invisible decays of pseudoscalar mesons and axion-like particles by detecting forward protons with reduced energy in coherent exclusive electroproduction, potentially improving existing bounds on meson branching ratios by up to four orders of magnitude and probing new physics couplings in the 0.1–2 GeV mass range.
