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.

At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.

Probing the CP Property of ALP-photon Interactions at Future Lepton Colliders

This paper investigates how future lepton colliders can probe the CP properties of axion-like particle (ALP) interactions with photons by analyzing the azimuthal angle difference between final-state electrons in the e+e−→e+e−γγe^+e^- \to e^+e^- \gamma\gamma process, demonstrating that this observable can distinguish between CP-conserving, CP-violating, and mixed interaction structures with projected sensitivities exceeding current electron electric dipole moment constraints.

Radiative corrections to the nucleon isovector gVg_V and gAg_A

This paper calculates enhanced electroweak, QCD, and QED radiative corrections to the nucleon coupling constants gVg_V and gAg_A, providing updated relations between lattice-QCD and physical values that yield a total correction of approximately 3.5% to 5.6% and predict a physical axial charge gAg_A of 1.265(26) or 1.240(9) depending on the input methodology.

Flash from the Past: New Gamma-Ray Constraints on Light CP-even Scalar from SN1987A

This paper establishes new constraints on the mixing angle of light CP-even scalars with the Standard Model Higgs boson by analyzing non-detections of gamma-ray excess from SN1987A in historical Solar Maximum Mission satellite data, which would have resulted from scalars produced via nucleon bremsstrahlung and subsequently decaying into photons.

System size and event shape dependence of particle-identified balance functions in proton-proton collisions at s=13\sqrt{s} = 13 TeV using PYTHIA 8 and EPOS models

This study utilizes PYTHIA 8 and EPOS-LHC models to demonstrate that particle-identified balance functions in 13 TeV proton-proton collisions exhibit distinct dependencies on event multiplicity and spherocity, revealing that while PYTHIA 8 reflects fragmentation-dominated dynamics, EPOS-LHC captures collective effects like radial flow and diffusion that mimic heavy-ion behavior, thereby offering a powerful tool to disentangle hadronization mechanisms and medium-like collectivity in small collision systems.

Witten-O'Raifeartaigh potential revisited in the context of Warm Inflation

This paper demonstrates that the Witten-O'Raifeartaigh potential can support a unified cosmological model where Warm Inflation occurs on its steep left wing and transient dark energy arises on its flatter right wing, provided the potential is normalized differently for each era and the quintessence field incorporates dissipative dynamics to sustain slow-roll.
