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 demonstrates that in both Loop Quantum Cosmology and its modified variant, a combined potential featuring an ekpyrotic component can effectively suppress shear during the bounce to resolve anisotropy issues, while subsequently allowing the inflationary component to dominate and produce a sufficiently long inflationary phase.
This paper characterizes the coherent and stochastic signals produced by ultralight dark matter with quadratic couplings in pulsar timing arrays, finding that while current PTA observations can compete with other probes for coherent signals, they remain less sensitive than equivalence principle tests for stochastic signals.
This paper demonstrates that electroweak penguin-tree relations can be derived using only isospin symmetry rather than full flavor SU(3) symmetry, revealing that applying these stricter SU(2) relations to the puzzle significantly exacerbates the discrepancy with the Standard Model to a 4–5 level.
This paper investigates the intrinsic connection between Majorana neutrino mass generation and neutron-antineutron oscillation within various extensions of the Georgi-Glashow grand unification model that break lepton number, demonstrating how the dynamics responsible for neutrino masses inevitably induce baryon-number-violating transitions.
This paper demonstrates that proton decay constraints severely limit the size of the M-theory interval in heterotic string theory, ruling out the possibility of a micron-scale dark dimension and restricting its length to approximately meters or smaller.
This paper demonstrates that assuming a Majorana nature for singlet-doublet dark matter significantly expands the viable parameter space for relic density and direct detection compared to the Dirac scenario, allowing for dark matter masses up to 1750 GeV and mixing angles up to 0.45 through the inclusion of conversion-driven processes.
This paper assesses the sensitivity of upcoming IceCube and KM3NeT measurements of Galactic neutrinos to new physics, demonstrating that a global network of neutrino telescopes can probe quasi-Dirac neutrino mass-squared differences in the range of to and neutrino decay mass-over-lifetime ratios exceeding .
This paper presents a global fit of transition form factors using lattice QCD data, light-cone sum rules, and experimental measurements to constrain the inverse moment of the -meson light-cone distribution amplitude and determine the CKM matrix element .
This paper calculates eleven energy-momentum tensor form factors for the deuteron using impulse approximation to map out its internal mass, momentum, stress, and force distributions, revealing how antisymmetric stress components relate to spin reorientation via torsion and how non-radial forces arise from tensor interactions and spin-orbit coupling.
Using PYTHIA 8.316 simulations, this study demonstrates that the QCD analogue of the inverse Compton effect in quark-gluon scattering increasingly dominates secondary particle production in proton-proton collisions as energy rises from 30 GeV to 14 TeV, particularly influencing transverse momentum and central pseudorapidity distributions due to enhanced small-x gluon interactions.
