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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes a minimal extension of scalar singlet dark matter with a charged scalar portal that revives the experimentally excluded mass region, enables hypercharge symmetry non-restoration and baryogenesis via a strong first-order phase transition, and predicts gravitational wave signals detectable by upcoming observatories like LISA, BBO, and DECIGO.
This paper introduces a scalable, autoregressive transformer-based framework for generating full collider events using residual-quantized tokens, demonstrating that token-level loss effectively predicts physical fidelity and enabling fast, ML-based surrogates to overcome bottlenecks in High-Luminosity LHC simulations.
This paper proposes a fermionic inelastic dark matter model mediated by a dimension-6 operator that naturally explains a high-energy nuclear-recoil event observed by LUX-ZEPLIN and the correct thermal relic density for dark matter masses between 0.2 and 1 without requiring fine-tuning.
This paper demonstrates that a TeV-scale muon collider, by generating a high-energy neutrino flux from muon decays, can achieve a neutrino trident production rate of approximately events per year in a 10 kg detector, enabling high-precision Standard Model tests and significantly extending the sensitivity to new physics such as the boson.
This paper demonstrates that continuous spin particles are absent in all perturbative superstring theories, thereby establishing their non-existence as a general low-energy prediction of these frameworks.
This paper presents an open-source Retrieval Augmented Generation (RAG) pipeline that leverages hybrid retrieval and a Large Language Model to synthesize concise, citation-grounded literature summaries from over 230,000 high-energy and astroparticle physics papers, thereby overcoming the limitations of traditional keyword search in navigating the field's vast literature.
This paper proposes that infrared-only tidal disruption events, occurring in dense, obscured nuclear environments, can efficiently accelerate cosmic rays and produce high-energy neutrinos through radiative compression, potentially contributing significantly to the diffuse neutrino flux and becoming detectable via joint stacking searches with future multi-km³ neutrino observatories.
This paper demonstrates that incorporating nuclear size corrections into the statistical hadronization model fails to consistently describe (hyper)nucleus production data across various collision systems, whereas the uncorrected model supports the interpretation that these nuclei form from compact multi-quark configurations that expand after hadronization.
This paper investigates higher-order QCD corrections in Higgs boson production via weak-boson fusion with decays to bottom quarks, demonstrating that while fixed-order calculations yield large corrections due to the interplay with fiducial cuts, employing a parton-shower-matched description significantly improves perturbative convergence.
This paper reviews the celestial sphere approach to QCD infrared divergences, demonstrating how universal soft-gluon phenomena map to a two-dimensional conformal field theory where single-emission logarithms are absorbed into the coupling scale while multiple emissions reveal complex operator product expansion structures that break holomorphic factorization.
