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 proposes a novel cosmological model where dynamical dark energy arises from the non-perturbative topological structure of the QCD vacuum without introducing new fields, demonstrating that this physically motivated scenario fits current observational data as well as standard models while naturally predicting phantom-crossing behavior without theoretical instabilities.
This paper investigates the discovery potential at the High-Luminosity LHC for non-standard decays of vector-like top partners into charged Higgs bosons and subsequent tau leptons within a 2-Higgs doublet model, demonstrating that the resulting final state can probe vector-like top partner masses up to approximately 1.9 TeV.
This paper presents a comprehensive study of hybrid stars composed of hadrons, leptons, and quarks within a relativistic mean-field framework, utilizing QCD sum rule-derived coupling constants to construct equations of state for both hadronic and quark phases and subsequently predicting mass-radius relations, tidal deformabilities, and particle distributions for comparison with multimessenger astrophysical observations.
This paper proposes a simple Dirac scoto-seesaw framework based on an anomaly-free charge assignment that simultaneously explains neutrino mass hierarchies through tree-level and radiative mechanisms, stabilizes dark matter via a residual symmetry, and relaxes collider constraints on the boson to broaden the viable parameter space for dark matter phenomenology.
This study demonstrates that in Energy-Momentum Squared Gravity, the trace anomaly of dense matter continues to organize the interior curvature profiles of neutron stars into systematic bands similar to General Relativity, despite the theory's nonlinear coupling between matter and geometry.
This paper utilizes a new hadronic collision Monte Carlo generator, QGSb, to investigate how specific model modifications affect predictions for extensive air shower characteristics—namely shower maximum depth and ground-level muon number—while analyzing the underlying physics and consistency with accelerator data to address uncertainties in cosmic ray composition studies.
This paper investigates the key features and surprising statistical properties of deep learning from a physics-informed perspective, with a specific focus on neural scaling laws and their interplay with the inductive biases relevant to physics problems.
This paper investigates the Witten effect within the Standard Model to classify dyonic charge lattices and -angle periodicities, demonstrating that the electromagnetic subgroup emerges prior to electroweak symmetry breaking and revealing that a single axion is insufficient to fully restore CP invariance.
This paper presents comprehensive theoretical calculations for LDMX, DarkSHINE, and LOHENGRIN experiments that extend beyond standard coherent Bethe-Heitler scattering by including higher-order electromagnetic and kinetic mixing effects, finding that while these contributions have limited impact on signal and background predictions, the LOHENGRIN experiment specifically requires a hadronic calorimeter extension to effectively veto diffractive scattering backgrounds.
This paper presents a novel technique utilizing form factors and the universality of infrared divergences to compute new three-loop renormalization constants for the axial anomaly and pure-singlet contributions to the quark axial-vector form factor in a mixed gauge theory.
