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 introduces a time-resolved statistical framework that leverages Earth's rotation and detector visibility to efficiently distinguish between dark matter decay and isotropic origins for ultra-high-energy neutrinos, demonstrating that incorporating temporal information significantly reduces the number of events required to exclude the dark matter hypothesis.
This paper proposes a novel statistical framework utilizing daily modulation from Earth-shielding effects in low-threshold liquid-noble detectors to disentangle and validate sub-GeV dark matter interactions with both electrons and nuclei, demonstrated through a case study of DarkSide-50 data.
This paper investigates how a GeV-scale Higgs-portal scalar can drive an early matter-dominated era and links the resulting reheating temperature to long-lived particle signatures, demonstrating that FCC-hh displaced-decay searches can probe transition temperatures up to the electroweak scale.
This paper introduces the "well-tempered likelihood," a method that adjusts likelihood-based confidence intervals by scaling them with a goodness-of-fit statistic to prevent overconfidence and ensure robust constraints when statistical models are misspecified.
This paper investigates the dynamical stability, thermodynamic properties, and observational signatures of charged Reissner-Nordström black holes in bumblebee gravity, revealing how Lorentz symmetry breaking and electric charge influence quasinormal modes, greybody factors, and phase transitions.
This paper establishes robust cosmological constraints on hidden sectors containing magnetic monopoles, demonstrating that symmetry-breaking scales above approximately 100 PeV lead to an overclosed Universe unless the sectors are absent, the monopoles are absent, the post-reheating temperature remains below the symmetry-breaking scale, or the abundance is diluted by early matter domination.
This study demonstrates that to remain consistent with observations of stellar streams and gravitational lensing, the primordial power spectrum must feature a log-normal bump with an amplitude of at least at wavenumbers between 10 and 30 Mpc, as this specific enhancement is required to reproduce the observed halo and subhalo structures.
Using lattice QCD simulations with four physical-mass quark flavors, this study determines the momentum fractions and angular momentum contributions of quarks and gluons in the proton, confirming that both the momentum and spin sum rules are satisfied in the continuum limit.
This paper demonstrates that binary black hole mergers with strong magnetic fields and high remnant spins can accelerate charged particles to ultra-high energies (-- eV) via the Bañados--Silk--West mechanism, identifying these events as promising sources of ultra-high-energy cosmic rays.
This paper presents a comprehensive analysis of angular coefficients in Z and W boson production at hadron colliders, demonstrating that combining NNLL transverse-momentum resummation with NLO fixed-order calculations systematically improves the description of experimental data in the intermediate region without degrading agreement elsewhere.
