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.
By applying the Gaussian Expansion Method to the Silvestre-Brac potential within a diquark model, this study reveals that centrifugal forces acting on light degrees of freedom invert the expected mass hierarchy in doubly-heavy tetraquarks, a robust mechanism confirmed across various heavy-hadron systems.
This paper presents the latest hybrid determination of the hadronic vacuum polarisation contribution to the muon magnetic moment by the BMW and DMZ collaborations, achieving 0.45% precision and overturning the theoretical consensus to resolve the long-standing discrepancy with experimental measurements.
This paper demonstrates that in the Minimal Left-Right Symmetric Model with generalized parity, the low-energy Dirac CP-violating phase alone can successfully generate the observed baryon asymmetry of the universe, offering a testable link between neutrino physics and cosmology that depends critically on the neutrino mass ordering and scale.
Using QCD sum rules, this study interprets the resonance as an -wave molecular pentaquark state and calculates its mass and decay properties, finding results consistent with experimental data.
This paper investigates the weak interaction's contribution to the ground-state hyperfine splitting of muonium by calculating amplitudes for one- and two-quantum exchanges mediated by Z and W bosons, as well as deriving one-loop corrections to the photon and Z boson propagators.
This paper derives the non-local non-stabiliserness (magic) in gluon and graviton scattering, demonstrating that the helicity basis naturally manifests this quantum resource for standard interactions but fails to do so when new physics operators are introduced.
This paper develops a quantum kinetic theory for Quantum Chromodynamics that incorporates leading-order collision terms to reproduce the Boltzmann equation at lowest order and predict spin polarization of quarks and gluons at next order, revealing distinct behaviors for vortical versus non-vortical gradients and a mechanism for spin-orbital angular momentum conversion via inelastic collisions.
Using 1.4 years of atmospheric neutrino data from the first six detection units of the KM3NeT/ORCA detector, this study finds no evidence for isotropic Lorentz invariance violation and establishes competitive new limits on relevant coefficients.
This paper develops a unified phenomenological framework for missing-energy searches involving light spin-1 gauge bosons coupled to electroweak-anomalous currents, deriving their effective interactions from minimal anomalon spectra and evaluating constraints from rare flavor and electroweak processes alongside direct searches.
Using high-resolution Lyman- forest data and new Sherwood-Relics simulations, this study presents updated constraints on the isocurvature fraction of post-inflationary axion-like particles, revealing a tentative detection of a non-zero contribution while establishing competitive upper bounds that surpass previous large-scale structure limits.
