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 a multi-agent framework utilizing task decomposition and quantity-grounded semantic differencing to enhance the transparency, reproducibility, and reliability of scientific analyses generated by LLMs by explicitly identifying and resolving ambiguities in user instructions and implementation assumptions.
This paper presents an analytical framework that transforms the Lamb shift energy calculation into a one-dimensional momentum-space convolution to derive model-independent constraints on Yukawa-type fifth forces using hydrogen and deuterium spectroscopy, revealing a resonance-like cancellation at a critical range and highlighting current spectroscopic precision as the primary limitation for detecting such interactions.
This study demonstrates that incorporating scalar bosonic dark matter into two-fluid color-flavor-locked strange quark star models allows for the existence of massive compact objects in the lower mass-gap region, such as the secondary component of GW190814, while maintaining qualitative compatibility with tidal deformability constraints from GW170817, noting that the dark matter component does not always form an extended halo as this depends on the model parameters.
This paper discusses the separation of energy scales in soft hadron scattering, distinguishing between the scale where total cross-sections begin to rise (governed by absorption features) and the asymptotic scale (dominated by unitarity effects), while establishing a relationship between them through the transition from shadow to reflective scattering.
This paper introduces a background-independent one-loop renormalization framework that analytically isolates and absorbs UV divergences into local counterterms using universal WKB behavior, thereby yielding finite, model-independent expressions for primordial scalar and tensor spectra without requiring specific background evolution or full field dynamics.
This paper presents the first automated, resonance-aware MC@NLO matching of NLO QCD+EW corrections to an interleaved QCD+QED parton shower, specifically developed to eliminate spurious higher-order terms from recoil assignments and validated through predictions for Drell-Yan lepton pair production.
The paper introduces **ggxy**, a fast and flexible C++ library that calculates Next-to-Leading Order (NLO) QCD corrections for gluon-initiated top-mediated processes like , , and with full top-quark mass dependence, featuring analytical approximations for two-loop virtual amplitudes and an interface to Powheg for parton shower matching.
This paper demonstrates that the initial anisotropy in heavy-ion collisions induces a measurable spin alignment in vector mesons ( and ) via quark or hadron coalescence, where the sign of the alignment () serves as a distinctive signature to differentiate between production mechanisms involving bare vector coupling versus those with spin-orbit coupling or pseudoscalar-meson coalescence.
This paper interprets CP bias in proton-antiproton diffractive dissociation as an apparent, non-unitary effect arising from either environmental interactions or intrinsic stochasticity consistent with CPT invariance, rather than fundamental CP violation, and outlines the conditions and future experiments needed to distinguish between these mechanisms.
This paper utilizes the relativistic distorted-wave impulse approximation (RDWIA) with two-particle-two-hole meson-exchange currents to successfully describe flux-integrated inclusive and pionless neutrino scattering cross sections on argon within MicroBooNE experimental uncertainties, while also comparing these results with carbon data to investigate nuclear effects.
