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 how relativistic effects, specifically Wigner rotations and nonrelativistic dipole-dipole interactions, generate and modify spin correlations and quantum coherence in Møller scattering and related processes, ultimately demonstrating that final spin states encode scattering information and resolving discrepancies in inelastic electron-positron scattering.
This paper investigates the electric dipole moments of muons and taus within the B-L supersymmetric standard model, demonstrating that both the traditional -term and model-specific CP-violating parameters can produce significant contributions, with muon EDMs potentially falling within the sensitivity of upcoming Phase II experiments and tau EDMs reaching magnitudes around .
This paper predicts the existence of ten narrow, isoscalar five-flavor () molecular pentaquark states in the 7.72–7.96 GeV range, along with two additional deeply bound states, by applying local hidden gauge and heavy-quark symmetries to meson-baryon interactions, thereby extending previous hidden-charm studies to the bottom sector and offering specific targets for LHCb searches.
This paper presents global Bayesian limits on Majorana neutrino masses by combining latest neutrinoless double-beta decay experimental data with ab initio nuclear matrix elements, revealing that current experiments likely lack the sensitivity to probe the neutrino mass regime allowed by oscillation data while demonstrating that next-generation searches across four key isotopes could collectively cover the inverted mass ordering.
This paper computes generalized susceptibilities and correlations of conserved charges up to eighth order within the Polyakov chiral SU(3) quark mean field model, comparing vacuum-inclusive and no-sea variants to reveal distinct behaviors in chiral-deconfinement splitting, off-diagonal correlator amplitudes, and higher-order kurtosis ratios as functions of temperature and baryon chemical potential.
This paper presents the first NNLO QCD predictions for production at hadron colliders based on a direct computation of the required two-loop amplitudes in the generalised leading-colour limit, addressing previous reliance on dynamical approximations for this complex process.
This paper resolves discrepancies in the literature regarding the effective scalaron-photon coupling in gravity by demonstrating that the trace anomaly, arising from the transformation between Jordan and Einstein frames, cancels the diagrammatic contribution in the limit of light scalaron mass, thereby leading to a vanishing effective coupling and a suppressed decay rate into photons.
By applying redshift-dependent corrections for progenitor age to the Pantheon+ supernova catalogue, the study reveals that the universe's monopole deceleration parameter shifts to positive values, indicating cosmic deceleration while leaving the local dipole anisotropy unchanged.
This paper calculates significant kinematic corrections proportional to and for the short-distance expansion of quasi(pseudo) GPDs, thereby reducing a major uncertainty in lattice QCD calculations and extending their applicability to larger momentum transfers for imaging the proton's three-dimensional structure.
This paper investigates the Einstein-de Haas effect in an expanding quark-gluon plasma using a quasiparticle model, revealing that the induced angular velocity grows with proper time and reaches significant magnitudes near the crossover temperature, thereby establishing a distinct transition between spin-dominated and inertia-dominated regimes driven by magnetic fields.
