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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This review article presents an overview of dileptons as penetrating probes that, by escaping the fireball without final-state interactions, provide a space-time-evolution weighted average of the properties of hot and dense QCD matter created in heavy-ion collisions.
This paper presents a hybrid neural-network method implemented in C++ that significantly reduces the storage, memory, and initialization costs of multidimensional double parton distribution grids by compressing most data into a neural model while storing only a sparse set of high-accuracy residuals, achieving a 10.6-fold reduction in disk footprint with minimal impact on evaluation speed.
This paper proposes a method to construct a finite, weighted reference sample that globally maximizes the likelihood for learned density ratios, demonstrating that such a small dataset can accurately reproduce expected test statistic scans and distributions typically requiring millions of simulated events in neural simulation-based inference.
Using fully nonlinear numerical relativity, this study reveals that while dust fluid simulations of primordial black hole formation in a matter-dominated universe require significantly larger initial amplitudes to avoid premature computational crashes, collisionless particle simulations allow for black hole formation at thresholds an order of magnitude lower than previous analytic estimates.
This paper investigates how the ground-state properties of the meson evolve as the number of light-quark flavors () approaches the conformal window, revealing that while chiral symmetry restoration and deconfinement occur at a critical flavor number, the meson's survival is governed by the divergence of the confinement length scale rather than mass crossing, resulting in a larger, rounder object with flattened form factors and an expanding charge radius.
This paper presents a pedagogical visualization of Bell inequalities using a "twin" analogy for entangled particles, demonstrating how the space of local models forms a tetrahedron within the quantum elliptope and the broader no-signalling cube in the space of mixed moments.
This paper investigates solar neutrino spin-flavor precession within a three-flavor framework, demonstrating that while resonant conversions are suppressed, nonresonant Majorana conversion offers a distinctive antineutrino signal that the Jinping Neutrino Experiment could detect to set stringent new limits on neutrino magnetic moments.
This study utilizes Bayesian inference on NICER mass-radius data to demonstrate that while dark energy cores significantly alter and can be constrained by neutron star observations, asymmetric dark matter cores remain observationally indistinguishable from purely baryonic stars for mass fractions up to 5%, implying that mass-radius measurements alone are insufficient to detect the latter.
This paper demonstrates that in Einstein-Cartan spinor gravity, spinor loops generate the kinetic and mass terms for both the local-Lorentz gauge field and the vierbein, thereby inducing a complete effective action comprising a cosmological constant, Einstein-Hilbert term, Weyl-squared term, and torsion dynamics that respects general-coordinate and local-Lorentz gauge invariances.
This study utilizes the chiral quark model combined with the decay mechanism to provide a coherent interpretation of the low-lying spectrum, successfully identifying most observed states as -mode excitations while suggesting that is not a pure three-quark state and assigning and to and configurations, respectively.
