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 introduces a velocity-dependent two-scale model to demonstrate that cosmic string networks with small-scale structure generally attain a linear scaling regime through gravitational backreaction, albeit with significantly reduced energy density and root-mean-squared velocity compared to smooth strings.
This paper establishes a general, relativistically covariant theoretical framework for the semi-inclusive deep-inelastic scattering cross section and spin observables on a polarized spin-1 target, expressed in terms of invariant structure functions and valid across all deep-inelastic final-state regions.
This paper develops a light-front theoretical framework for semi-inclusive deep-inelastic scattering on a polarized deuteron with spectator nucleon tagging, deriving tagged structure functions and spin asymmetries that highlight the role of the deuteron's D-wave component and provide essential tools for future experiments at Jefferson Lab and the Electron-Ion Collider.
This paper demonstrates that in holographic light-front QCD, a tower of hard exclusive amplitudes with a Poisson-distributed Fock expansion generates a spectral function that encodes the full Regge spectrum and provides an analytic representation of physical form factors invariant under continuous deformations of the average parton multiplicity.
This paper demonstrates the feasibility of simulating the thermalization dynamics of minimally truncated SU(2) lattice gauge theory on current noisy quantum hardware by successfully matching error-mitigated results from IBM quantum computers with classical simulations for chains of up to 101 plaquettes.
This paper presents a fully analytical framework for calculating spin density matrices in cascade decays of baryon-antibaryon pairs produced in electron-positron annihilation, revealing that maximal parity violation yields fully polarized but non-entangled final states, while -conserving charge-conjugate decays of polarized pairs generically exhibit quantum entanglement amplification.
This paper extends the phenomenological analysis of a flavor-dependent gauge extension of the Standard Model by relaxing the assumption of a strong scalar hierarchy, thereby revealing a new two-component dark matter scenario comprising both fermionic and scalar particles alongside the previously studied purely fermionic case, and identifying viable parameter spaces consistent with relic density and direct detection constraints.
This paper investigates the puzzling observation that dielectron emission temperatures in the intermediate mass region remain constant at approximately 287 MeV across a wide range of collision energies at RHIC and LHC, despite the expectation that initial parton plasma temperatures should rise significantly with increasing bombarding energy.
Using a Monte Carlo event generator with -factorization, the study demonstrates that the observed stronger-than-linear growth of D-meson yields in high-multiplicity pp and pPb collisions is reproduced by various initial-state spatial distributions, indicating that this observable is insufficient for distinguishing the specific matter geometry within the proton.
This paper extends the Left-Right Symmetric model with a sterile neutrino dark matter candidate and modular symmetry to investigate how varying modular weights influence the relic abundance of dark matter and the mechanism of leptogenesis.
