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.
Using the miniDSE scheme of Dyson-Schwinger equations, this study demonstrates that including dynamical charm quark fluctuations in QCD induces a moderate but noticeable shift of approximately 2–3% to lower chemical potential in the location of the critical endpoint, highlighting the significance of heavy-flavor dynamics in precision studies of the QCD phase structure.
Employing the STOchastic LAttice Simulation (STOLAS) code, this study investigates the spatial profiles and topological structures of curvature perturbations in multi-waterfall hybrid inflation models, validating the stochastic-N algorithm while revealing how stochastic noise drives defect reconnection and imposes upper bounds on perturbations in cubic potential scenarios.
This paper demonstrates that while relaxing the assumption of equal on-shell and off-shell Higgs coupling modifiers in Standard Model extensions can allow for a larger total width, realistic constraints still limit this increase to at most a factor of two compared to the standard indirect bounds.
This thesis establishes a rigorous, algorithmic framework for restoring gauge and BRST invariance in chiral gauge theories using the BMHV scheme with non-anticommuting , successfully demonstrating its feasibility through the complete 4-loop renormalisation of an Abelian theory and the 1-loop renormalisation of the full Standard Model.
This paper presents a combined analytical and numerical study of field theory cosmic strings, demonstrating that while translational Goldstone modes lack nontrivial curvature corrections, massive shape modes couple to worldsheet curvature to induce parametric instabilities that transfer energy between sectors.
This paper derives one-loop quark contributions to effective vertices coupling magnetic fields and the condensate within a magnetized quark-gluon plasma, identifying specific effects that could signal QGP creation in heavy ion collision experiments.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
This paper investigates eV-scale sterile neutrino mixing schemes (3+1, 1+3, and 2+2) in light of short-baseline anomalies and global fit data, finding the 3+1 model most viable and constraining the sterile neutrino mass to approximately 4.7 eV for both normal and inverted hierarchies through neutrinoless double beta decay analysis.
This paper applies the Principle of Maximum Conformality to the next-to-next-to-leading-order perturbative QCD calculation of the rare Higgs decay , successfully eliminating renormalization and factorization scale ambiguities to provide a robust, scale-invariant prediction for the decay width that offers a precise probe for the charm-quark Yukawa coupling.
This paper presents a novel numerical integrator for evaluating Feynman master integrals by treating branch cuts differently, achieving significantly faster computation times in double and quadruple precision that enable efficient on-the-fly calculations in Monte Carlo generators and the generation of grids for complex topologies.
