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 presents a global Bayesian analysis using a Color Glass Condensate framework and Gaussian-process emulators to demonstrate that correcting for electromagnetic dissociation effects in LHC data resolves previous tensions between proton and nuclear datasets, enabling a consistent simultaneous description of coherent and incoherent diffractive J/ψ photoproduction in both γ+p and γ+Pb collisions.
This paper investigates the first-order phase transition ending thermal inflation by combining semi-analytic and numerical methods to model bubble nucleation and growth, ultimately predicting a stochastic gravitational-wave background detectable by future observatories like BBO and DECIGO.
This review paper synthesizes the experimental evidence for the hypothetical X17 particle, explores theoretical models that could explain its existence, evaluates its implications for the Standard Model, and outlines future experimental directions.
This paper demonstrates that the emission of numerous light string axions from primordial black holes can significantly enhance superradiant dark matter production and the formation of "micro-boson stars" by increasing black hole spin, while simultaneously ensuring that the resulting axion contribution to relativistic degrees of freedom at recombination remains negligible.
This paper demonstrates that the four-fold discrepancy in recent limits on the decay arises from the choice of kinematic variables, showing that fine-grained binning in the reconstructed di-neutrino invariant mass () is essential for resolving narrow axion signals while BDT-based approaches dilute sensitivity, thereby advocating for the publication of likelihoods in physical variable spaces to ensure robust reinterpretability.
This paper employs three-point QCD sum rules, including higher-order vacuum condensate contributions, to calculate the form factors for and transitions, which are then used to predict the decay widths and branching ratios of various nonleptonic and semileptonic decay channels to aid in the study of heavy-quark dynamics and potential new physics beyond the Standard Model.
This paper proposes a heterotic string-inspired two-field warm inflation model involving an axion and a dilaton, demonstrating through numerical analysis that viable inflation is predominantly axion-driven and effectively single-field, with thermal corrections generally suppressing the role of the dilaton.
This paper proposes a high-quality axion model where the axion arises as a pseudo-Nambu-Goldstone boson of baryon number symmetry in a composite sector (such as SQCD with ), naturally suppressing dangerous symmetry-breaking operators due to the high dimension of the baryon operator while generating the required coupling to gluons through flavor symmetry anomalies.
This paper proposes a radiative lepton mass model based on a non-invertible gauging of a fusion rule, where charged-lepton masses arise from dynamical symmetry breaking while neutrino masses are generated without breaking the rule, leading to testable predictions for lepton flavor violations, anomalous magnetic moments, electric dipole moments, and neutrinoless double beta decay that align with experimental data.
This paper proposes that dark matter is not a new particle but an emergent, dynamical state arising from the interaction between a three-form gauge field and the cosmic fluid, offering a unified framework for the dark sector that suggests conventional dark matter searches may be futile.
