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 time-dependent mixing model involving a late phase transition that allows sterile neutrinos to serve as dark matter while simultaneously generating neutrino masses, effectively circumventing astrophysical X-ray constraints that typically rule out such scenarios in standard type-I seesaw frameworks.
This paper argues that recent ACT results favoring larger e-fold numbers in Starobinsky inflation necessitate an efficient spectator-assisted preheating stage to achieve viable reheating temperatures and support primordial black hole formation.
This paper offers a pedagogical overview of hadronic jets and event shapes at electron-positron colliders, covering jet definitions, perturbative QCD predictions, jet substructure techniques, and key topics like flavoured jets and Higgs decays.
By comparing gamma-ray spectra from nuclei in Supernova 1991T with terrestrial values, this study finds no significant energy shift, thereby constraining the evolution of a quintessence-like pseudoscalar dark energy field and confirming its consistency with a cosmological constant.
This paper presents the first constraints on the Thomson optical depth to reionization derived solely from the Lyman- forest, yielding values of for both physically motivated and symmetric reionization models, and demonstrates the potential for future CMB-independent constraints on the epoch of reionization using large-scale structure probes.
This paper utilizes cosmological observations to establish the strongest constraints to date on strong, long-range dark forces by demonstrating that attractive and repulsive self-interactions between fermionic dark matter particles, mediated by a light scalar, significantly alter background and perturbation dynamics, thereby ruling out a wide range of previously unconstrained parameter spaces.
Using first-principle numerical simulations of SU(3) lattice Yang-Mills theory, this study investigates the free energy and angular momentum of rotating hot gluon matter, revealing that both the specific moment of inertia and specific deformation exhibit negative values in the phenomenologically interesting temperature range above the phase transition before turning positive at higher temperatures.
This paper proposes that - and -violating parameters in the quark-gluon plasma enhance synchrotron radiation while suppressing its elliptic flow, offering a potential solution to the missing direct photons puzzle in heavy-ion collisions.
This paper presents the complete three-loop mixed QCD and QED corrections to on-shell quark mass and wave-function renormalization constants, deriving the corresponding relations between pole, , and masses as well as the quark-mass anomalous dimension.
Using lattice QCD with Nf = 2+1 flavors, the gradient flow method, and Bayesian model averaging, the authors calculate the nucleon's gluon momentum fraction to be 0.482(35) at a scale of 2 GeV.
