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 universal seesaw Pati-Salam model with a simple Higgs sector that unifies quarks and leptons into common multiplets, spontaneously breaks parity to solve the strong CP problem without an axion, and generates small Majorana neutrino masses through one-loop diagrams while remaining consistent with observed fermion masses.
The paper discusses the dominance of the imaginary part of the elastic scattering amplitude and advocates for an approximation method based on this dominance.
This paper investigates constraints on scalar Loryons within a Two Higgs Doublet Model, finding that while neutral singlet Loryons up to 700 GeV remain viable, those containing charged scalars are severely restricted by LHC data, unitarity, and Higgs decay observables.
This paper proposes a minimal generalized Proca model that realizes a phantom-divide crossing in dark energy while maintaining stability against ghosts and Laplacian instabilities, demonstrating that its flexibility in sound speed allows it to remain consistent with observational constraints on matter growth and light bending.
This paper investigates the viability of light bino-higgsino dark matter within natural supersymmetry under recent experimental constraints, finding that while a small portion of the parameter space survives with a sub-dominant relic density, it will be fully tested by future High-Luminosity LHC searches.
This study utilizes an expanding elliptic fire-cylinder model to successfully describe the transverse momentum spectra and elliptic flow of light hadrons produced in peripheral Au+Au collisions across the RHIC Beam Energy Scan range, demonstrating that parameters constrained by pion data can consistently predict the behavior of kaons and protons without further adjustment.
This lattice simulation study reveals that weak acceleration in gluodynamics transforms the finite-temperature confinement-deconfinement phase transition into a spatial crossover where coexisting phases are separated by a boundary accurately described by the Tolman-Ehrenfest law, suggesting such spatial transitions may occur near Schwarzschild black hole horizons.
This paper introduces a novel eigenvalue technique to solve the adjoint Fokker-Planck equation for the probability distribution of inflationary e-folds, revealing a previously overlooked power-law intermediate regime in quantum diffusion and characterizing how constant drift potentials qualitatively alter the distribution's peak and tail behavior in narrow- versus broad-well limits.
This paper proposes a unified framework for the lineshape based on the mixing of a compact isosinglet and a molecular isotriplet via strong isospin breaking, demonstrating how their interference can explain experimental anomalies such as the enhancement of charged decays and distinctive distortions in spectra.
This paper presents a modernized, AI-ready release of approximately 660,000 reconstructed SLD electron-positron collision events and newly digitized internal documentation, converted from legacy formats to facilitate research in both particle physics and machine learning.
