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 study employs Bayesian inference to demonstrate that while jet quenching constraints across collision centrality are compatible, variations in beam energy and observable classes reveal distinct aspects of jet-medium interactions that limit predictive universality, motivating the use of leading-hadron-selected observables to bridge these gaps.
This paper investigates rare dileptonic decays of , , and baryons within the Type III Two-Higgs-Doublet Model, calculating key observables like branching ratios and forward-backward asymmetries using light-cone QCD form factors to compare predictions against Standard Model results and assess the model's viability for future experimental verification at LHCb and Belle II.
Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.
This brief review outlines the main theoretical frameworks for neutrino masses, with a specific focus on Majorana scenarios involving the spontaneous breaking of global lepton number and the phenomenological implications of the resulting massless Goldstone boson, the majoron.
This paper summarizes the ISO-BREAK 25 workshop held in Kielce in October 2025, which reviewed the current status of isospin-symmetry breaking observed by NA61/SHINE in nucleus-nucleus collisions, discussed its confirmation by other experiments, and outlined future experimental and theoretical priorities to explain this phenomenon.
This paper proposes a novel high-luminosity experimental approach using tagged hyperons produced in proton-proton collisions within a nested-target setup to precisely measure hyperon-nucleon interactions, thereby addressing the uncertainties in the equation of state that underlie the hyperon puzzle in neutron stars.
This study estimates pulsar beaming fractions across radio, X-ray, and gamma-ray bands using TeV-selected pulsar wind nebulae and unidentified sources, revealing survey-dependent variations likely caused by selection effects and pulsar age differences, which can be reconciled within a unified framework employing a time-dependent opening angle.
This paper presents a systematic study of semi-leptonic Higgs decays to electroweak gauge bosons at NLO QCD and electroweak accuracy, demonstrating that while finite fermion masses and higher-order corrections significantly modify angular observables, the process retains an effective two-qutrit description suitable for quantum tomography and entanglement analysis.
This paper presents the first beyond-next-to-leading-order study of the process by developing a complete four-dimensional tensor decomposition, evaluating one-loop polarized amplitudes analytically to higher orders in the dimensional regulator, and establishing an efficient numerical framework for five-point Feynman integrals to enable future NNLO predictions for radiative return processes.
This paper demonstrates that energetic final-state radiation induces decoherence and significantly reduces the entanglement of fermion-antifermion pairs produced at colliders, with statistically significant experimental signals predicted for current datasets from production at the LHC and production at Belle 2.
