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 investigates the detection of loosely bound composite dark matter that disassembles into cascades of constituents while traversing the Earth, proposing unique underground signatures such as non-collinear multiple scatters, time-separated events, and coincident signals across different laboratories.
The "Small Patch Hypothesis" proposes that the observed uniformity and flatness of our universe are not necessarily results of early-universe mechanisms like inflation, but are instead observational selection effects caused by the fact that we can only perceive a tiny, smooth portion of a much larger, pre-existing, and potentially non-flat spacetime.
This paper presents a model-independent global analysis of top-quark flavor-changing neutral current (FCNC) interactions by matching them to the SMEFT framework and utilizing diverse experimental constraints—including electric dipole moments—to derive stringent limits on Wilson coefficients and predict observable CP-violating effects for future collider searches.
This paper presents the recently completed calculations of three-loop unpolarized and polarized massive operator matrix elements and asymptotic Wilson coefficients for deep-inelastic scattering, while also providing efficient numerical representations of massless coefficients, splitting functions, and target-mass corrections to support QCD fitting.
This paper utilizes a form-invariant algebraic model to investigate the internal structure of and mesons by calculating their light-front wavefunctions, valence-quark generalized parton distributions (GPDs), and other related physical observables.
This paper provides the analytic three-loop virtual corrections to the helicity amplitudes for various four-lepton scattering processes in massless QED, expressed in terms of generalized polylogarithms.
This paper generalizes the double copy relationship from field theories to classical string theory by demonstrating how the motion of an open string in an abelian gauge field can be mapped to a closed string in a corresponding gravitational background.
This paper presents an analytical framework using a square-well potential to model short-range nucleon-nucleon interactions, providing a more accurate tool for proton-proton femtoscopy than the standard Lednicky-Lyuboshits approximation, especially for small source sizes.
The paper proposes two cost-effective, medium-baseline neutrino experiments—SINE (a surface scintillator detector) and UNDINE (a submerged water Cherenkov detector)—to study LHC-produced neutrinos and constrain neutrino cross sections and cosmic-ray physics.
This paper derives a first-principles factorization formula using Soft-Collinear Effective Theory (SCET) and boosted Heavy-Quark Effective Theory (bHQET) to describe the semileptonic decay of boosted, off-shell top quarks in annihilation, introducing a new "ultra-collinear-soft" (ucs) function to account for QCD interference and non-narrow-width effects.
