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 novel technique using form factors and infrared divergence universality to compute renormalization constants for the axial anomaly in a mixed gauge group, presenting new three-loop results for these constants and pure-singlet quark axial-vector form factor contributions.
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 method to distinguish between monochromatic signals from ultralight dark matter and gravitational waves in space-based interferometers like LISA and Taiji by utilizing null-response channels that remain blind to gravitational waves from specific directions while still detecting ultralight dark matter.
This paper proposes a heterotic string-inspired two-field warm inflation model involving an axion and a dilaton, demonstrating through numerical analysis that while multi-field dynamics are possible, viable solutions are predominantly axion-driven due to thermal corrections that typically suppress dilaton-dominated inflation.
This paper investigates the mass spectra and electromagnetic radiative decay widths of the triply heavy and baryons using a screened potential model within a quark-diquark framework, providing calculated results for excited states that are systematically compared with other theoretical predictions.
