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 employs Soft Collinear Effective Theory (SCET) to factorize polarized Deep Inelastic Scattering structure functions and near the limit, calculating one-loop matching coefficients and anomalous dimensions to sum Sudakov double logarithms and clarify the operator structure of twist-three contributions.
This paper critiques a recent study (arXiv:2507.07180) by arguing that its proposed ad-hoc symmetrization of Dirac neutrino amplitudes lacks physical justification and incorrectly violates lepton number conservation within the Standard Model.
This paper proposes using the one-point energy correlator (OPEC) in transversely polarized proton-proton collisions as a novel, infrared-and-collinear safe method to probe the nucleon's transversity distribution with a clean angular asymmetry over a wider kinematic range than traditional hadron transverse momentum measurements.
This paper investigates the prospects for detecting long-lived heavy neutral leptons (HNLs) at the high-luminosity LHC via an axion-like particle (ALP) portal, utilizing simulations for both far detectors and ATLAS while also evaluating sensitivities from dimension-8 operators in the limit of heavy ALP masses.
This paper analytically demonstrates that the variation of the quark-gluon plasma volume in ultracentral collisions depends on initial density fluctuations and is negligible when total entropy scales with the mass number, thereby establishing that measurements of average transverse momentum can probe detailed nuclear structure and pre-equilibrium dynamics.
This paper employs a constituent quark model with a Cornell-like potential to predict the masses and decay characteristics of exotic compact tetraquarks across light, charmonium-like, and fully-charm sectors, concluding that the observed state is unlikely to be a compact tetraquark.
This paper proposes a Tikhonov regularization-based toy model to solve the inverse source problem in femtoscopy, demonstrating the successful reconstruction of Gaussian and hybrid source functions from momentum-correlation data to enable future extraction of realistic hadron-pair source distributions.
This paper investigates the cosmological gravitational production of stable spin-3/2 particles, termed "raritrons," demonstrating that their ability to constitute dark matter depends critically on the mass hierarchy relative to the inflationary Hubble scale, which governs the sound speed of the longitudinal mode and can lead to significant enhancements in particle production, particularly for lighter masses or time-dependent mass scenarios.
This paper proposes that quantum entanglement serves as a unifying foundation for statistical and high-energy physics, arguing that systems naturally evolve toward a Maximal Entanglement Limit where thermalization and probabilistic behaviors emerge from the geometry of high-dimensional Hilbert spaces without requiring ergodicity or classical randomness.
This paper demonstrates that a minimally reconfigured version of CERN's existing NA62 experiment, operating in a future ECN3 beam-dump facility with an optimized geometric setup, can achieve highly competitive sensitivity for detecting feebly interacting particles in the MeV to GeV mass range immediately upon beam availability.
