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 employs the Method of Regions to demonstrate that kinematic dependence in spacelike-collinear splitting amplitudes, which violates strict factorisation, originates from a unique "hidden region" absent in the timelike limit, and proposes a general algorithm to identify such regions as the mechanism breaking analytic connection between crossing-related asymptotic limits.
This paper calculates a specific radiative-recoil correction of order to the Lamb shift in muonium, arising from radiative photon insertions in the heavy line of two-photon exchange diagrams, to support ongoing high-precision and experiments.
This paper presents a novel on-shell constructive formalism using Soper-Weinberg collinear spinors and Galilean symmetry to systematically derive complete leading and subleading massive collinear splitting functions for all Standard Model particles, thereby bridging the gap between massless amplitudes and finite-mass effects for precision collider physics.
This paper calculates substantial and positive next-to-next-to-leading order (NNLO) QCD corrections for pion- and kaon-induced exclusive Drell-Yan processes within the generalized parton distribution framework, establishing the necessity of including these higher-order effects for reliable theoretical predictions to match future J-PARC experimental data.
This paper investigates how Flavour Deconstruction extensions of the Standard Model generate detectable primordial gravitational waves through first-order phase transitions, revealing that while LISA detection is possible, the signals typically peak at higher frequencies better suited for mid-band observatories.
This paper utilizes high-resolution self-interacting dark matter (SIDM) simulations to demonstrate that the continuous evolution of halo properties through gravothermal processes, particularly core collapse, can explain the high densities of low-mass perturbers detected in strong gravitational lensing systems, thereby establishing lensing as a powerful probe of dark matter self-interactions.
This paper evaluates the potential of argon-based Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) experiments at major facilities like ORNL, LANL, and Fermilab to perform precision tests of Standard Model electroweak parameters and probe non-standard neutrino properties, including electromagnetic moments and non-standard interactions.
This paper presents a novel quantum simulation framework using Light-Front Quantization to calculate hadron fragmentation functions from first principles, demonstrating its feasibility through a classical proof-of-concept computation of charm-to-charmonium fragmentation that aligns with established perturbative results.
This paper re-evaluates the Galactic Center as a target for dark matter searches by employing advanced statistical methods to distinguish between a potential dark matter signal and a stellar population of millisecond pulsars, ultimately deriving stringent upper limits on the dark matter annihilation cross-section for masses below 300 GeV.
This paper investigates retardation models for hadronic quark interactions by adapting classical electrodynamics procedures to coordinate space, critically analyzing their quantum operator formulation, and demonstrating a substantial physical correspondence with tree-level Feynman diagram interactions.
