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.
The paper introduces \texttt{bsm_agent}, an open-source framework that integrates a deterministic Python backend for symbolic physics calculations with a large language model interface to automate the construction, validation, and analysis of Beyond the Standard Model theories through natural language interaction.
This paper demonstrates that current cosmological data do not generically exclude light sterile neutrinos but instead strongly disfavor fully thermalized scenarios, leaving partially populated or suppressed-abundance models viable depending on their specific production history and phase-space distribution.
The paper challenges the view that cosmology reveals a unique underlying reality, arguing instead that its objective content lies in cross-representational informational invariants, thereby redefining scientific progress as the refinement of accessible observational structure rather than convergence toward a fixed ontology.
This paper investigates how the presence of a massive dark sector fermion, rather than a massless neutrino, alters the kinematic and angular distributions of semileptonic decays within a general weak effective theory framework, thereby offering a systematic method to detect such new physics and assess its impact on the extraction of the CKM matrix element .
This paper provides quantitative analytical and numerical evidence from Type IIB Calabi-Yau compactifications that the proposed quantum gravity cutoff bound, , holds for both and axions even near the boundaries of the Kähler moduli space, thereby supporting its status as a general feature of extra-dimensional axions in quantum gravity.
This paper presents an LLM-powered pipeline that automates the extraction and integration of dark matter constraints from arXiv papers into community repositories, achieving high accuracy in coupling classification and curve reconstruction while highlighting the unresolved challenges of governing AI-generated scientific data.
This paper presents analytic next-to-next-to-leading-order QCD corrections for heavy-quark production in charged-current deep-inelastic scattering with exact charm mass dependence, expressing two-heavy-quark contributions via Goncharov polylogarithms and three-heavy-quark contributions via elliptic structures and rapidly convergent expansions for efficient numerical evaluation.
This paper investigates the gravitational form factors and generalized parton distributions of the deuteron using a hard-wall AdS/QCD model, demonstrating that the results align well with soft-wall model predictions and experimental data for the gravitational mean square radius.
This review examines recent DESI measurements suggesting a departure from the standard CDM model toward dynamical dark energy, exploring how different parametrizations and datasets influence this preference while analyzing how various beyond-CDM scenarios could explain these findings and potentially resolve existing cosmological tensions.
This paper investigates the feasibility of observing single hyperon production via lepton-nucleon deep inelastic scattering at colliders by calculating cross sections with various theoretical form factors, ultimately highlighting significant experimental challenges and theoretical uncertainties while suggesting that anomalous observations could signal new physics.
