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.

VALO1.0: New real-photon parton distributions with Monte Carlo uncertainties

This paper presents VALO1.0, a new set of leading-order and next-to-leading-order real-photon parton distribution functions determined via a global QCD analysis of photon structure function data, which utilizes Monte Carlo replicas to quantify experimental uncertainties and provides open-source tools for their application.

Simultaneous Dalitz-plot decomposition of the e+e−→J/ψ π π (KKˉ)e^+ e^- \to J/\psi \, \pi \, \pi \, (K \bar{K}) processes in the 4.13-4.36 GeV region using dispersive final-state interactions

This paper presents a joint dispersive analysis of e+e−→J/ψπ+π−e^+e^- \to J/\psi\pi^+\pi^- and J/ψK+K−J/\psi K^+K^- processes in the 4.13–4.36 GeV region, demonstrating that a single set of energy-independent parameters successfully describes the data only when including both resonant structures (Y(4220)Y(4220), Y(4320)Y(4320), Zc(3900)Z_c(3900)) and a non-resonant production mechanism subject to coupled-channel final-state interactions.

Current and future constraints on heavy New Physics from τ\tau weak dipole moments

This paper presents updated Standard Model predictions and comprehensive constraints on the τ\tau lepton's weak dipole moments using current data from the LHC and ZZ-pole observables, while projecting that future FCC-$ee$ and HL-LHC experiments will significantly enhance sensitivity to heavy New Physics, potentially making these moments the dominant probes for such operators.

Polarized and unpolarized synchrotron emission from dark matter in extragalactic targets

This study utilizes Planck microwave data to compute 95% confidence-level upper limits on dark matter annihilation and decay by analyzing both total and polarized synchrotron emission from five extragalactic targets, demonstrating that microwave polarimetry serves as a robust and complementary probe for constraining dark matter properties.

The three phases of self-gravitating scalar field ground states

This paper challenges the conventional assumption that ultralight dark matter halos universally possess spherically symmetric solitonic cores by demonstrating that strong repulsive interactions between multiple scalar fields can cause immiscibility, leading to diverse ground state phases dependent on mass, density, and interaction strength.

Neutrino mass and mixing, resonant leptogenesis and charged lepton flavor violation in a minimal inverse seesaw model with S4S_4 symmetry

This paper proposes a minimal inverse seesaw model with S4S_4 symmetry, characterized by only three parameters, which successfully explains neutrino oscillation data, predicts a normal mass ordering with specific CP and mixing angles, and accounts for the observed baryon asymmetry and charged lepton flavor violation within experimental limits.
