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 derives a generalized McLerran-Toimela formula showing that rotating plasmas emit significantly more soft photons than non-rotating ones due to leading-order one-loop contributions and superradiant amplification of specific modes, which in turn induces an instability in the magnetic fields generated during relativistic heavy-ion collisions.
This paper argues that Holographic Space Time models of black hole formation and evaporation do not exhibit the "memory burden" effect claimed in recent literature, as the specific definitions of energy and causality in these models, combined with Fermi's Golden Rule, prevent such macroscopic constraints on black hole lifetimes.
This paper employs light-cone sum rules with upgraded perturbative and higher-twist accuracy to calculate the strong and couplings, yielding precise numerical predictions and a universal static coupling that highlight significant heavy quark spin symmetry breaking effects.
Using the NOvA near detector, researchers achieved the most precise measurement to date of the muon antineutrino charged-current quasi-elastic cross section on hydrogen at an average energy of 1.9 GeV, obtaining a value of cm with sufficiently low non-flux uncertainties to enable future constraints on the absolute antineutrino flux.
This paper proposes a novel strategy to image the three-dimensional longitudinal structure of the quark-gluon plasma by comparing ultrarelativistic collisions of nuclei with similar masses but different shapes to isolate and remove nonflow correlations, thereby revealing previously inaccessible rapidity-dependent flow features.
This paper utilizes model-independent low-energy theorems derived from chiral symmetry breaking to compute pion matrix elements and decay rates in a uniform magnetic field, comparing these results with chiral perturbation theory, lattice QCD, and the Nambu-Jona-Lasinio model to highlight significant tensions between the latter and low-energy QCD.
This paper demonstrates that induced gravitational waves generated during an early matter-dominated phase can serve as a unique observational probe for thermal leptogenesis, with their frequency and amplitude directly correlated to the leptogenesis energy scale.
This study demonstrates through numerical simulations of the Gross-Pitaevskii-Poisson equations that while vortex formation is a universal outcome of Bose star mergers, the resulting vortex scale is inversely controlled by the strength of attractive self-interaction and directly controlled by the strength of repulsive self-interaction.
This paper demonstrates that non-thermal leptogenesis, driven by the decay of a heavy Higgs boson, can successfully generate the observed baryon asymmetry in a gauged extension of the Standard Model with an inverse seesaw mechanism, overcoming the strong washout effects of Yukawa couplings through a specific scalar mass tuning that allows for a reduced reheating temperature.
This paper proposes a unified framework for quantum chromodynamics in which topological gluon knots, characterized by the Hopf invariant within the Faddeev-Niemi effective theory, serve as the fundamental infrared degrees of freedom that simultaneously explain monopole condensation, Y-shaped baryon confinement, chiral symmetry breaking, and the origin of proton spin.
