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.

Virial theorem for rigidly rotating matter

This paper employs the virial theorem to derive scaling properties of the thermodynamic free energy for massless fermionic matter in rigid rotation, establishing that hydrodynamic descriptions require a specific hierarchy between the system's size and temperature, and demonstrating that thermodynamic variables depend on angular velocity through the product ΩR\Omega R, a finding consistent with recent lattice QCD simulations and used to estimate the light quark contribution to the moment of inertia in Quark-Gluon Plasma.

Joint constraints on cosmic birefringence and early dark energy from ACT, Planck, DESI, and PantheonPlus

This paper presents a joint analysis of ACT, Planck, DESI, and PantheonPlus data to constrain cosmic birefringence induced by early dark energy, finding that the combined dataset supports a higher Hubble constant (H0≈76.9H_0 \approx 76.9 km/s/Mpc) and a significant early dark energy fraction (fEDE≈0.23f_{\mathrm{EDE}} \approx 0.23).

Systematic study of lepton-flavor-violating dark matter interactions via indirect detection in effective field theories

This paper systematically constrains lepton-flavor-violating dark matter interactions within effective field theories by analyzing astrophysical photon and positron data from Fermi-LAT, INTEGRAL, XMM-Newton, and AMS-02, revealing that INTEGRAL provides the most stringent limits for dark matter masses below 20 GeV while AMS-02 dominates for higher masses across scalar, fermion, and vector candidates.

Charting doubly strange hidden-charm pentaquarks: An electromagnetic mapping of spin-12\frac{1}{2} and 32\frac{3}{2} states

This study presents the first systematic QCD light-cone sum rule investigation of the electromagnetic multipole structure, including magnetic dipole, electric quadrupole, and magnetic octupole moments, for doubly strange hidden-charm pentaquarks with JP=1/2−J^P = 1/2^- and 3/2−3/2^-, revealing significant sensitivity to internal color-spin correlations and charm-quark dominance while providing theoretical benchmarks for future experimental and lattice QCD validation.
