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 investigates the analytic structure of the partition function in a finite-volume mean-field QCD model to analyze the temperature dependence of Lee-Yang zeros and edge singularities, demonstrating that while finite-size scaling methods can successfully locate the critical point, accurate determination requires a careful treatment of corrections from irrelevant operators.
This paper presents a unified open quantum system framework based on the Lindblad equation to describe both the suppression and thermal recombination of charmonium and bottomonium states in ultrarelativistic heavy-ion collisions undergoing Bjorken expansion.
This paper proposes a hidden-sector dark matter model where the dark matter and Standard Model decouple at high temperatures yet evolve to similar temperatures at freeze-out, allowing for the observed relic abundance with standard annihilation cross sections while rendering direct detection and collider signals potentially unobservable due to extremely weak couplings.
This paper proves that a non-trivial quantum Yang-Mills theory must possess a mass gap arising from a constant tadpole term in the gluon self-energy, a conclusion derived from a novel constraint on QCD solutions within the Slavnov-Taylor identity framework that preserves perturbative renormalizability while addressing the Jaffe-Witten theorem.
This paper introduces an automated, iterative optimization technique using the MadAnalysis5 interface to systematically rank observables and select cuts, thereby enhancing the discovery potential for new physics signals like singly charged Higgs bosons in 2HDM scenarios compared to traditional cut-and-count methods.
Using 13.6 TeV proton-proton collision data, the FASER experiment reports the first differential measurement of the muon neutrino interaction cross section and flux in the TeV energy range, confirming Standard Model predictions and distinguishing contributions from pion and kaon decays.
This paper utilizes N-body and semianalytic simulations to demonstrate that the orbital contraction of globular clusters due to dynamical friction serves as a robust, independent probe for confirming the presence of dark matter halos in ultradiffuse and dwarf galaxies like NGC5846-UDG1 and Fornax.
This paper introduces a real-time Wigner-functional lattice framework with a connected-cluster survival criterion to accurately characterize false-vacuum decay rates across the quantum-to-thermal crossover, revealing that global-survival methods can underestimate rates at high temperatures due to multi-seed dynamics while transient effects contaminate fraction observables at low temperatures.
This paper investigates the one-loop effective potential of the r0 (or "GOOFy") symmetric two-Higgs Doublet Model and a minimal symmetric model, concluding that the symmetry remains valid at the one-loop level provided the UV cutoff squared transforms non-trivially under r0 and the minimal model includes two real fields.
This paper investigates the potential of the proposed ESSnuSB far detector to constrain non-standard neutrino interactions using atmospheric neutrinos, demonstrating that it can set competitive upper bounds on interaction parameters while highlighting the experiment's complementarity with accelerator-based programs and its impact on mass ordering and octant sensitivities.
