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 demonstrates that in compact spatial dimensions below a critical volume, false vacuum decay is mediated by a novel homogeneous bounce solution—distinct from Coleman's bubble—that exponentially enhances the decay rate and applies to phenomena such as the Schwinger effect in compact space.
This paper explores a dark matter model where a fermionic dark matter particle simultaneously satisfies existing collider and direct detection constraints while serving as a source for observable charged lepton flavor violation signals, such as and conversion.
This paper proposes a two-loop radiative neutrino mass model based on modular and symmetries that successfully explains neutrino oscillation data and charged lepton masses while predicting observable lepton flavor violation and providing viable scalar and fermionic dark matter candidates consistent with cosmological and experimental constraints.
This paper proposes an extended flavor symmetry model with two Higgs doublets and a triple inverse seesaw mechanism that simultaneously explains neutrino oscillation data, provides a viable dark matter candidate, and generates the observed baryon asymmetry via TeV-scale resonant leptogenesis.
This paper presents an approximate formula for the Shannon entropy of the negative binomial distribution, which remains valid within approximately 20% accuracy even for extreme parameter values.
This paper demonstrates that primordial black holes can still form during slow first-order phase transitions via an early matter-dominated era induced by slow reheating, a mechanism previously thought to be ruled out, resulting in the production of black holes with large spins.
This paper presents a comprehensive next-to-leading order QCD study of the process in the di-lepton channel at 13.6 TeV within the SMEFT framework, demonstrating that consistently including higher-order corrections and dimension-6 operators in both top-quark production and decay is crucial for accurately predicting kinematic distributions and interpreting LHC Run III data.
The paper introduces CaloArt, a large-patch x-prediction Diffusion Transformer that achieves state-of-the-art high-granularity calorimeter shower generation with high physics fidelity and low computational cost, eliminating the need for pretrained latent tokenizers.
This paper investigates how dimension-6 SMEFT operators, particularly those inducing anomalous chromo- and weak dipole moments, modify quantum information observables such as entanglement, discord, and Bell parameters in top quark pair production at the LHC, demonstrating that these QI metrics offer a unique and complementary probe for distinguishing CP-even and CP-odd anomalous interactions.
This paper establishes a complete set of explicit coupling conditions derived from particle content in the mass basis that fully diagnose tree-level unitarity in theories with spin-1 particles, demonstrating that these constraints are captured by amplitudes up to five points and revealing that scalar-free theories necessitate an infinite tower of vectors and fermions to maintain unitarity.
