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 that non-minimal coupling between a massive scalar field (potentially constituting dark matter) and the Ricci scalar induces tachyonic instabilities and scalarization in neutron stars, enabling them to support maximum masses exceeding even when the equation of state is softened by the presence of hyperons.
This paper calculates the one-loop electric dipole moments of leptons and the neutron within the N-B-LSSM framework using the Mass Insertion Approximation, deriving analytical expressions that reveal their dependence on specific CP-violating phases and demonstrating that the model's predictions can satisfy current experimental limits across a reasonable parameter space.
This paper demonstrates that loop-induced group-like symmetries, termed "groupification," remain exact in theories with fusion algebras derived from finite group conjugacy classes, thereby ensuring the naturalness of non-invertible selection rules and revealing approximate discrete symmetries that control coupling magnitudes in heterotic string theory.
This paper investigates the impact of higher-order perturbative (up to NNLO) and nonperturbative (target mass and higher-twist) QCD corrections on proton structure functions and parity-violating electron asymmetry, providing numerical results for JLab energies to aid future analyses at the Electron Ion Collider and EicC.
This study utilizes Thermal QCD Sum Rules to investigate the molecular state, revealing that its mass, decay constant, and width remain stable up to approximately 120 MeV before undergoing significant changes near the deconfinement temperature, thereby offering critical insights into QCD phase transitions and the behavior of exotic mesons in hot, dense matter.
This paper investigates whether a massive sterile neutrino could explain the discrepancy between -meson and -baryon decay anomalies by revisiting the semileptonic sum rule, concluding that the induced effects are too small to resolve the tension and thus the sum rule remains a robust consistency check for experimental data.
This paper provides a comprehensive functional framework for non-Abelian gauge theories that utilizes BRST and anti-BRST symmetries within background field gauges to construct a unique, gauge-invariant, and process-independent effective charge for Yang-Mills theory, thereby offering a unified description of its dynamics from the ultraviolet to the infrared regime where dynamical mass generation occurs.
This paper investigates whether positron injection from sources responsible for the 511 keV excess can explain the anomalous ionization rates in the Galactic Center's Central Molecular Zone, concluding that while such positrons produce higher ionization than other candidates, they are insufficient to fully account for the observed anomaly.
This paper proposes a "shaft-warm" inflationary potential derived from Two-time physics and demonstrates that its slow-roll scenario within the Randall-Sundrum II framework yields a tensor-to-scalar ratio consistent with BICEP2 and Planck data, allowing for a five-dimensional Planck mass estimate of GeV.
This paper investigates how CET Omega, an informational extension of quantum field theory, introduces a doubly logarithmic correction to the early-Universe radiation density that modifies WIMP freeze-out dynamics, thereby offering a consistent explanation for a tentative 20 GeV gamma-ray excess while remaining compatible with current cosmological constraints.
