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.

Towards compressed baryonic matter densities: D meson diffusion

This paper investigates the spatial diffusion and momentum transport coefficients of D mesons in dense nuclear matter using a chiral SU(3) hadronic model and kinetic theory, revealing that these properties decrease rapidly at low densities and more mildly at high densities, offering insights relevant to future heavy-ion collision experiments.

Conservative Black Hole Scattering at Fifth Post-Minkowskian and Second Self-Force Order

Using worldline quantum field theory and advanced computational techniques, this paper calculates conservative black hole scattering contributions at fifth post-Minkowskian and second self-force orders, resolving a spurious velocity divergence through a novel prescription to ensure consistency with radiative effects and post-Newtonian limits.

The next-to-leading order of the differential cross section of the subprocess of annihilation of quark-antiquark pair of prompt photon production in proton-proton collisions at NICA energies

This paper investigates the significant next-to-leading order (NLO) contributions to the differential cross-section of prompt photon production via quark-antiquark annihilation in proton-proton collisions at NICA energies, demonstrating that these corrections constitute approximately 15% of the leading order results and are strongly influenced by longitudinal proton polarization, with findings validated through PYTHIA 8.316 and POWHEG BOX Monte Carlo simulations.

How invisible can QCD axions be? From Supernova emission to Cherenkov signals

This paper investigates the production of maximally invisible QCD axions in core-collapse supernovae to derive SN 1987A cooling constraints and emission spectra, while simultaneously evaluating their detectability prospects in Cherenkov detectors to establish a robust lower bound on the overall observability of QCD axions.
