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.
By reformulating the Standard Model using complex quaternions to derive magnetic moments for fermions and bosons that couple to neutral pseudovector magnetic fields, this paper proposes a dynamical explanation for the parity asymmetry observed in charged weak interactions.
This paper introduces a "spectral dispersion" bootstrap strategy that combines de Sitter spectral decomposition with dispersion relations to efficiently compute loop-level cosmological correlators by reconstructing them from on-shell nonlocal signals and quasinormal modes.
This paper demonstrates that thermal effects in a minimal one-scale dark-sector gauge theory significantly alter the decay dynamics of metastable -strings by favoring thermally induced nucleation over zero-temperature monopole nucleation, thereby shifting the viable parameter space for explaining the nanohertz gravitational wave background observed by Pulsar Timing Arrays toward lower dark fine-structure constants and higher monopole-to-string-tension ratios.
This paper proposes a fixed-order perturbative on-shell construction of scattering amplitudes using BCFW-generated trees and integrated vacuum pairs, successfully reproducing the known one- and two-loop all-plus four-gluon amplitudes up to order through a polygon-organized inclusion-exclusion framework.
This paper investigates majoron dark matter within a high-scale seesaw framework, analyzing its production mechanisms and observational constraints across pre- and post-inflationary scenarios to demonstrate its viability as a cosmological probe of lepton number breaking and thermal leptogenesis.
This paper investigates the low-energy phenomenology of a minimal flavor-deconstructed framework in the lepton sector, demonstrating that next-to-leading order effects induce physical CP-violating phases and flavor misalignment that make future searches for conversion and electron electric dipole moments powerful probes of multi-10 TeV scales beyond direct collider reach.
This paper demonstrates that in the general Two-Higgs-Doublet Model with a scalar potential possessing two local minima, the masses of all scalar particles are bounded provided the dimensionless quartic couplings satisfy perturbativity constraints.
This paper presents the next-to-next-to-leading logarithmic (NNLL) collinear resummation of projected -point energy correlators up to , incorporating newly computed two-loop jet functions and leading non-perturbative corrections, thereby establishing quantitative control over these observables for future precision extractions.
This paper constructs an explicit model where a Dirac fermion dark matter candidate is boosted via semi-annihilation into anti-dark matter and neutrinos, simultaneously generating radiative neutrino masses at the two-loop level, and demonstrates that a mediator mass of MeV enhances the elastic scattering cross section to levels detectable by future experiments like DUNE and DARWIN.
This paper elucidates how the Chiral Quark Soliton Model (CQSM), by uniquely incorporating non-local quark-quark correlations arising from spontaneous chiral symmetry breaking, successfully predicts various nucleon parton distribution functions, particularly the flavor asymmetry of sea-quark distributions, outperforming traditional effective meson theories like the Skyrme model.
