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 Higgsformer, a transformer-based model that successfully classifies versus events directly from raw inner tracker hits, achieving performance comparable to traditional object-based reconstruction pipelines while bypassing intermediate physics object reconstruction.
This paper calculates the one-loop QCD corrections to the single transverse spin asymmetry in unweighted Drell-Yan processes using collinear twist-3 factorization, demonstrating gauge invariance and the consistent removal of divergences while presenting finite hard coefficients for the relevant parton convolutions.
This paper demonstrates that normalizing flow models trained on previous posteriors can serve as effective, flexible priors for sequential Bayesian inference in high-dimensional spaces, provided that target distributions are unimodal and robust sampling algorithms are employed.
This paper investigates the stochastic gravitational wave background from primordial black holes in dwarf galaxies, revealing that while hierarchical binary mergers dominate the total signal, hyperbolic encounters provide an earlier, continuous subdominant background that becomes relatively more significant as the population evolves, with distinct spectral features potentially detectable by future observatories like LISA and ET.
This paper provides a detailed description of a method for calculating high-order QED vacuum polarization corrections up to order in the Coulomb field of a pointlike nucleus by reducing the problem to free QED Feynman graphs with up to eight independent loops.
This paper investigates the semileptonic decay using the Hypercentral Constituent Quark Model to calculate baryon masses and Heavy Quark Effective Field Theory form factors with subleading corrections, ultimately determining the decay width and branching ratio for comparison with other theoretical approaches.
This paper analyzes constraints on axion-photon coupling from global 21-cm signal observations and identifies viable parameter regions where parametric resonance can simultaneously satisfy observational limits and support the formation of primordial magnetic fields and direct collapse black holes.
This paper proposes using naive -odd Collins-Soper moments ( and ) in high-energy Drell-Yan processes at the high-luminosity LHC to probe dimension-8 $CP$-odd semi-leptonic four-fermion operators, potentially constraining new physics scales in the few-TeV range.
This paper reviews the current state of the QCD phase diagram by synthesizing insights from lattice simulations, effective field theories, and chiral models to reconstruct the full phase structure for physical quark flavors and constrain matter properties in neutron star cores.
This paper presents a manifestly Lorentz invariant reformulation of top-quark condensation for the Higgs boson, utilizing an extended internal wave-function and a gauge-invariant absence of "relative time" to establish a novel, nontrivial vacuum structure analogous to a relativistic BCS condensate.
