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 paper demonstrates that quantum-information-motivated observables, particularly the spin correlation measured as a function of visible invariant mass in dileptonic top-quark pair events at the High-Luminosity LHC, significantly enhance the sensitivity to invisible new physics and the discrimination of mediator couplings compared to traditional rate and kinematic analyses.
This paper investigates a novel high-frequency gravitational wave source arising from the microscopic associated production of particles and gravitons during runaway bubble collisions in cosmological first-order phase transitions, offering a potential multiband signature that links gravitational radiation to new particle production such as dark matter.
This paper extends Hamiltonian truncation effective theory to two-dimensional Yukawa theory with fermions and logarithmic UV divergences, successfully demonstrating the convergence of bound state energy levels and mapping their evolution from weak to strong coupling regimes.
This paper presents the implementation, optimization, and validation of a multidimensional general-relativistic Boltzmann solver for neutrino transport that extends the \texttt{Gmunu} code to discretize the full 6D phase space, achieving quadratic convergence, significant computational speed-ups through Legendre expansion techniques, and results consistent with the M1 scheme in core-collapse supernova simulations.
This paper utilizes time-resolved polarization measurements of the repeating fast radio burst FRB 20220912A from the FAST telescope to set upper limits on the coupling constant of extragalactic axion-like dark matter, offering a complementary approach to galactic probes for detecting these particles on intergalactic scales.
The paper introduces HyPER, a novel hypergraph-based neural network architecture that outperforms existing state-of-the-art techniques in reconstructing short-lived particles from complex collider events while demonstrating superior parameter efficiency.
Core-collapse supernovae serve as the Universe's most powerful neutrino factories, emitting vast amounts of energy that, when observed by modern detectors, offer critical insights into stellar dynamics, neutron star formation, and potential new physics.
FIRE 7 is a major update to the Feynman integral reduction program that introduces automatic reduction via a modular arithmetic approach, enhances classical rational polynomial performance, and includes improved presolve algorithms and new command-line tools to streamline IBP reduction tasks.
This study extends the chiral quark soliton model to include a flavor-singlet pseudoscalar field generated by the chiral anomaly, revealing that while the anomaly-induced field enhances quark helicity and its associated mass suppresses this effect in favor of orbital angular momentum, these modifications result in only modest redistributions that do not qualitatively alter the conventional nucleon spin decomposition.
This paper investigates the hyperfine structure of , , and mesons using a QCD-inspired Cornell potential model with Gaussian-smeared spin-spin interactions and Dalgarno-Lewis analytic wavefunctions to provide stable, testable benchmarks for upcoming spectroscopy measurements.
