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 employs both machine learning techniques and an extended analytical mass formula to predict the mass spectra of fully-heavy baryons and exotic pentaquarks, offering complementary insights that align with existing experimental data and guide future searches for unobserved states.
The paper proposes "Unified Flavor," a framework where hierarchical Yukawa couplings and CP violation emerge from TeV-scale vectorlike fermion chains on a -lattice governed by a single flavon, successfully reproducing quark and lepton mass spectra while simultaneously addressing flavor constraints, strong CP, and offering testable predictions for future experiments.
This paper applies an effective field theory formalism to two-meson tau decays, concluding that future experiments with 5% precision on modes can test the maximum allowed CP rate asymmetry to either validate or refute the BaBar anomaly in decays.
This paper investigates energy-momentum tensor form factors and spatial spin density distributions in the nucleon using a quantized Skyrme model with vector mesons, demonstrating that while global nucleon properties remain invariant, the choice of pseudogauge (canonical versus Belinfante) significantly alters the local interpretation of spin and momentum densities.
This paper presents a forecast study demonstrating that a stacking analysis of very-high-energy gamma-ray observations from active galactic nuclei located behind galaxy clusters can probe Axion-Like Particle dark matter in the to eV mass range, achieving sensitivity to ALP-photon couplings as low as GeV.
This paper proposes that the Dark Technicolour paradigm, utilizing the Extended Most Attractive Channel hypothesis across three confining gauge sectors, revitalizes conventional Technicolour dynamics to generate Standard Model fermion masses and resolve the Flavor Problem through a hierarchical structure of multifermion condensates.
This paper introduces a novel class of critical unstable qubits characterized by orthogonal energy and decay-width vectors, revealing their unique coherence-decoherence oscillations and defining anharmonicity observables to quantify these effects within neutral-meson systems.
This paper investigates neutrino flavor evolution in high-flux astrophysical environments like supernovae and neutron star mergers, demonstrating that non-forward scattering and many-body dynamics lead to rapid energy and flavor equilibration, which significantly impacts nucleosynthesis and terrestrial neutrino observations.
This paper presents a coherent S-matrix treatment of the entire neutrino experimental chain that reveals non-factorizable corrections arising from spin and angular correlations, which introduce significant systematic shifts in energy spectra and enable the direct measurement of Majorana CP phases, thereby challenging the standard factorization assumption crucial for next-generation precision neutrino physics.
This paper introduces a path integral-based method to directly compute reduced density matrices in open quantum systems, applying it to a scalar field model and a neutrino toy model to demonstrate how initial Fock state correlations and lighter neutrino masses lead to significant distortions in particle number probabilities due to environmental interactions.
