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.

Nonmaximal symmetry breaking patterns in the supersymmetric su^(8)kU=1\widehat {\mathfrak{s} \mathfrak{u}}(8)_{k_U =1} theory

This paper investigates nonmaximal symmetry breaking patterns within a supersymmetric su^(8)kU=1\widehat {\mathfrak{s} \mathfrak{u}}(8)_{k_U=1} theory, demonstrating that specific patterns allow for gauge coupling unification below the Planck scale while explaining fermion mass hierarchies, whereas a distinct pattern is ruled out due to the presence of unrealistic massless vectorlike quarks.

Long-term neutrino emission from a core-collapse supernova with axion-photon coupling

This study employs long-term general-relativistic simulations to demonstrate that axion-photon coupling can induce detectable cooling effects in the late-phase neutrino signals of core-collapse supernovae, potentially allowing future observations by Super-Kamiokande to identify axion-like particles even with coupling constants below conventional energy-loss limits.

NNLO QCD corrections to γγQQˉ\gamma \gamma \rightarrow Q\bar{Q} from Local Unitarity combined with Coulomb resummation and NLO EW effects

This paper presents state-of-the-art NNLO QCD predictions for heavy-quark pair production in direct photon fusion by applying the Local Unitarity formalism to handle infrared singularities and combining these results with NLO electroweak corrections and NLP Coulomb resummation for top, bottom, and charm quarks.

Long-lived axionlike particles from electromagnetic cascades

This paper demonstrates that considering axionlike particle production from the full electromagnetic shower in beam dump targets, rather than just primary beams or specific meson decays, yields order-of-magnitude enhancements in detectable signals, thereby significantly expanding the sensitivity reach of the SHiP and BDX experiments to previously unexplored regions of ALP parameter space.

Test of the GENIE neutrino event generator against reduced cross sections extracted from 16{}^{16}O (e,ep)(e,e'p) data

This paper utilizes precise semiexclusive electron scattering data on oxygen-16 to test and identify deficiencies in the nuclear ground state and final state interaction models within the GENIE neutrino event generator, demonstrating that these models fail to accurately reproduce measured reduced cross sections across all kinematic regions.

Decay matrix of B-\bar{B} mixing: Mixing of dimension-seven operators into dimension-six operators under renormalization

This paper establishes a methodology for handling the renormalization of dimension-seven operators in BsB_s-Bˉs\bar{B}_s mixing by demonstrating that their infrared-finite one-loop corrections in the MS\overline{MS} scheme can be absorbed into finite counterterms proportional to dimension-six operators, thereby preserving power counting and constraining the definition of evanescent operators.

Concurrence fill and mode distribution of entanglement in neutrino oscillation

This paper demonstrates that in three-flavor neutrino oscillations, the system forms a W-type entangled state with vanishing genuine tripartite tangle, while deriving experimentally accessible measures like concurrence fill and symmetric invariant that quantify distributed entanglement and reveal distinct energy-dependent patterns, particularly near maximal mixing, which can be probed using DUNE long-baseline simulations.

Viability of Sub-TeV Higgsino Dark Matter with Nearly Mass-Degenerate Sleptons

This paper demonstrates that sub-TeV higgsino dark matter, with masses as low as approximately 400–500 GeV, remains a viable candidate in the MSSM through slepton coannihilation, provided that specific gaugino mass sign configurations (particularly M1/M2<0M_1/M_2 < 0) induce destructive interference to suppress spin-independent scattering cross sections below the stringent LZ-2024 direct detection limits.

A light DM model for large BK+\mboxinvisibleB \to K + \mbox{invisible} and Kπ+\mboxinvisibleK \to \pi + \mbox{invisible} decays and its implications for BsBˉsB_s-\bar B_s mixing and neutron EDM

This paper proposes a light dark matter model within a two-Higgs-doublet framework to explain recent deviations in rare meson decays, demonstrating that while neutral Higgs contributions to the neutron EDM are suppressed by cancellations lifted by QCD evolution, charged scalar contributions and specific CP-violating phases can generate a neutron EDM consistent with current experimental bounds while also predicting non-negligible effects on BsBˉsB_s-\bar B_s mixing.
