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 numerically investigates electron-positron pair production in strong oscillating electric fields with multi-pulse structures, revealing that varying the inter-pulse delay induces a characteristic time-domain multi-slit interference pattern in the production probability.
This paper demonstrates that while naive application of the Casas-Ibarra parametrization with 1-loop corrections leads to incorrect neutrino oscillation predictions, a modified approach that reabsorbs these corrections into the right-handed neutrino mass matrix yields consistent results, while also establishing that heavy neutral lepton searches are insensitive to such corrections and that the decay provides competitive constraints for masses above 100 GeV.
This paper constructs an A4-based flavor symmetry model within the type-I seesaw framework that utilizes mu-tau reflection symmetry to naturally predict maximal atmospheric mixing and a maximal Dirac CP phase, while also successfully accommodating the observed non-maximal deviations in these parameters through a two-parameter numerical analysis consistent with current global neutrino oscillation data.
This paper presents a fast, high-fidelity generative model based on score-driven diffusion and the Point-Edge Transformer architecture that successfully simulates realistic, high-multiplicity heavy-ion collision events through a two-stage training strategy, demonstrating its potential to replace computationally intensive traditional simulations.
This paper proposes a novel two-loop mechanism for low-scale leptogenesis driven by resonant thermal lepton-flavour coherences, which successfully generates the matter-antimatter asymmetry for both Dirac and Majorana singlet neutrinos with GeV-scale masses without requiring significant mass degeneracy.
This paper investigates the classical stability of a non-topological string in the minimal 331 model derived from an toy model and concludes that the string is only stable near the semilocal limit, suggesting such defects are unlikely to exist in unified theories based on Lie algebras.
This paper introduces a novel MERA-inspired tensor network autoencoder for collider jet anomaly detection, demonstrating that its locality-preserving hierarchical structure and disentangling layers provide a superior inductive bias for reconstructing jet data compared to dense and tree-based architectures, particularly under strong compression.
This paper demonstrates that a non-supersymmetric model extended with vector-like fermions and additional scalar fields can simultaneously explain the observed 125 GeV Higgs signal strengths and the 95 GeV excesses reported by LEP and CMS through a systematic analysis of mixed neutral CP-even Higgs states.
This paper demonstrates that quantum gravitational memory-burden effects suppress the high-energy tail of Hawking radiation from evaporating primordial black holes, thereby reducing their total luminosity and systematically weakening the constraints on their dark matter fraction derived from IceCube neutrino observations.
This paper calculates direct detection constraints on inelastic Dirac dark matter with a scalar mediator and leptophilic couplings, demonstrating that the p-wave velocity suppression of annihilation opens viable MeV-GeV mass parameter space and that liquid-xenon experiments like XENON1T, PandaX-4T, and LZ can constrain sub-MeV mass splittings via spin-independent dark matter-electron scattering.
