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.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper presents an Effective Field Theory study of the process at the Future Circular Collider (FCC-$hh$), demonstrating its unique capability to probe anomalous and couplings through a comprehensive collider analysis of the final state.
This paper proposes a TeV-scale baryogenesis scenario based on Dirac leptogenesis with resonantly enhanced CP asymmetry, which predicts observable decay asymmetries at colliders and a singlet scalar dark matter candidate consistent with thermal relic abundance.
This paper demonstrates that incorporating infrared and collinear safety along with E(2) and O(2) equivariance into graph neural networks for quark-gluon discrimination enhances model stability and interpretability by directly aligning learned latent representations with established QCD observables like Energy Flow Polynomials.
This paper calculates the next-to-leading order hard function for electroproduction within TMD factorization, analyzes the operator structure and phenomenological role of the TMD shape function, and provides predictions for the unpolarized differential cross-section at the future Electron-Ion Collider in the low-transverse-momentum regime.
This paper presents a Markov Chain Monte Carlo analysis of proton parton distribution functions using diverse experimental data and next-to-next-to-leading order QCD calculations to demonstrate how the Bayesian framework provides a statistically rigorous method for determining uncertainties, handling non-Gaussianities, and establishing well-founded tolerance criteria for the Hessian method.
This paper investigates the cosmological observational signatures of a hypothetical late-time breaking of symmetry, proposing that the resulting high-energy photon and neutrino spectra—dominated by thermal production from frictional bubble wall interactions—could serve as detectable "doomsday" signals reaching observers before the destructive vacuum transition itself.
This paper investigates the sensitivity of a future 250 GeV collider to CP-violating and CP-conserving anomalous Higgs-gauge couplings within the SMEFT framework, demonstrating that utilizing beam polarization and spin-correlation asymmetries across dominant Higgs decay channels can achieve sub-percent precision on dimension-6 operator coefficients, provided systematic uncertainties are controlled below the few-percent level.
This paper utilizes LHC dijet measurements, incorporating two-loop renormalization group effects, to establish constraints on ten third-generation four-quark operators, yielding nominal or comparable bounds for bottom-quark operators while leaving limits on the remaining operators weak.
This paper reviews the theoretical and experimental status of the predicted sign reversal of Boer-Mulders functions between semi-inclusive deep-inelastic scattering and Drell-Yan processes, demonstrating that current data supports this reversal for proton valence quarks while highlighting future prospects for testing it in pions at the Electron-Ion Collider.
