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.
This paper resolves the hyperfine puzzle by demonstrating that a minimax variational calculation based on the exact Dirac equation suppresses the effective magnetic moments of fermions at small radii, thereby preventing atomic collapse and ensuring the stability of hydrogen, positronium, and other two-fermion Coulombic systems.
This paper investigates the radiative corrections to reflection symmetry, demonstrating that the resulting low-energy predictions for the effective Majorana neutrino mass remain consistent with global neutrino oscillation data and the current upper bounds set by the KamLAND-Zen collaboration.
This paper utilizes the novel \pythiaPB\ framework to investigate non-perturbative QCD effects and soft-gluon dynamics in low-transverse-momentum Drell-Yan production, revealing a specific center-of-mass energy dependence of the intrinsic transverse momentum distribution and highlighting the spectrum's sensitivity to the transition between perturbative and non-perturbative regimes at high energies.
This study presents the first observation of Leggett-Garg inequality violation in polarized muon spin precession by analyzing Fermilab Muon data, achieving a significance that demonstrates the potential for high-precision measurements of temporal quantum correlations with improved detector modeling.
This paper investigates warm fermionic dark matter produced via freeze-in in a minimal Higgs portal scenario with low reheating temperatures, finding that velocity-suppressed production necessitates higher reheating temperatures than scalar models and results in a non-thermal momentum distribution that excludes fermion masses below approximately 100–180 keV via Lyman- constraints.
This paper investigates whether the next-generation helioscope IAXO can distinguish between signals from single versus multiple axion species by analyzing spectral signatures of axion flavor oscillations and mapping detection prospects in multi-axion parameter spaces.
This paper demonstrates that CPT violation can mimic the CP-violating phase in long-baseline neutrino experiments, potentially obscuring true measurements, and proposes using atmospheric neutrino data from IceCube and KM3NeT to constrain such violations and ensure unambiguous CP phase determination.
This paper utilizes gauge/string duality to construct conformal moments of unpolarized gluon GTMDs at strong coupling, demonstrating that these moments factorize into universal soft factors and stripped amplitudes while revealing how holographic backgrounds dictate infrared falloffs and enable a unified description of hadron tomography, rapidity evolution, and Reggeization relevant to the Electron-Ion Collider.
This paper investigates composite neutrino models where an inverse seesaw mechanism with anomalous scaling dimensions suppresses light neutrino masses while generating enhanced electromagnetic dipole moments, leading to distinctive single- and multi-photon radiative signatures in MiniBooNE and MINERvA experiments that serve as a novel probe of partial compositeness.
This paper investigates spin correlations and quantum entanglement in top-quark pair production at polarized photon colliders, demonstrating that while next-to-leading order QCD corrections significantly enhance the total cross section, they minimally affect spin observables, with entanglement and Bell nonlocality proving strongest near the production threshold and highly sensitive to beam polarization.
