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.

Fluctuations and correlations of conserved charges in the Polyakov chiral SU(3) quark mean field model

This paper computes generalized susceptibilities and correlations of conserved charges up to eighth order within the Polyakov chiral SU(3) quark mean field model, comparing vacuum-inclusive and no-sea variants to reveal distinct behaviors in chiral-deconfinement splitting, off-diagonal correlator amplitudes, and higher-order kurtosis ratios as functions of temperature and baryon chemical potential.

NNLO QCD predictions for ttˉWt\bar t W production at hadron colliders

This paper presents the first NNLO QCD predictions for ttˉWt\bar t W production at hadron colliders based on a direct computation of the required two-loop amplitudes in the generalised leading-colour limit, addressing previous reliance on dynamical approximations for this complex process.

Effective scalaron--photon interaction in f(R)f(R) gravity

This paper resolves discrepancies in the literature regarding the effective scalaron-photon coupling in f(R)f(R) gravity by demonstrating that the trace anomaly, arising from the transformation between Jordan and Einstein frames, cancels the diagrammatic contribution in the limit of light scalaron mass, thereby leading to a vanishing effective coupling and a suppressed decay rate into photons.

Finite-tt and target mass corrections for the short-distance expansion of quasi(pseudo) GPDs

This paper calculates significant kinematic corrections proportional to t/Pz2t/P_z^2 and mN2/Pz2m_N^2/P_z^2 for the short-distance expansion of quasi(pseudo) GPDs, thereby reducing a major uncertainty in lattice QCD calculations and extending their applicability to larger momentum transfers for imaging the proton's three-dimensional structure.

Einstein-de Haas effect and induced rotation in an evolving magnetized QCD matter

This paper investigates the Einstein-de Haas effect in an expanding quark-gluon plasma using a quasiparticle model, revealing that the induced angular velocity grows with proper time and reaches significant magnitudes near the crossover temperature, thereby establishing a distinct transition between spin-dominated and inertia-dominated regimes driven by magnetic fields.

Confronting fuzzy dark matter with the rotation curves of nearby dwarf irregular galaxies

While fuzzy dark matter provides an excellent fit to the rotation curves of nearby dwarf irregular galaxies with an axion mass of approximately 2×10−232\times10^{-23} eV, the model is ultimately ruled out by significant tensions (≳5σ\gtrsim5\sigma) regarding the observed core scaling relations and the suppression of the linear power spectrum.

Nonperturbative effects in triple-differential dijet and Z+jet production at the LHC

This paper investigates the impact of nonperturbative effects on triple-differential dijet and Z+jet production using Monte Carlo event generators, revealing significant process-dependent differences that motivate a proposed triple-differential measurement of the underlying event in Z+jet production to resolve whether this non-universal behavior exists in nature.

Flavour and Electroweak Precision Constraints on a Simplified Dark Matter Model with a Light Spin-0 Mediator

This paper systematically constrains the parameter space of a simplified dark matter model featuring a light spin-0 mediator (mass < 10 GeV) by integrating flavor physics, electroweak precision data, fixed-target experiments, and cosmological bounds, while specifically assessing its potential to explain recent Belle-II results on invisible B-meson decays.
