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.

This paper investigates the impact of a circularly polarized laser field on top quark decay within the type-I two Higgs doublet model, demonstrating that specific laser parameters can significantly enhance the branching ratio of the channel to 0.97, thereby surpassing the standard decay and offering a promising strategy for detecting charged Higgs bosons.
This paper extends the Koopman-von Neumann-Sudarshan Hilbert space formulation to relativistic QCD, demonstrating that the covariant Wigner operator is fundamentally a quantum probability amplitude projected onto phase space, thereby offering a unified framework that clarifies the origin of nonclassical features like negativity and establishes a transparent foundation for parton distribution functions.
This paper employs machine-learning-style optimization, featuring a novel singular-value-based optimizer and uncertainty estimation, to numerically explore the landscape of two-dimensional conformal field theories with central charges between 1 and 8/7, identifying candidate spectra in a previously uncharted region and suggesting a tighter constraint on the spectral gap near .
This paper investigates how tidal interactions with the Milky Way and stellar self-gravity affect ultra-light dark matter constraints derived from dwarf galaxies, finding that despite these systematics, dark matter masses between and eV remain in tension with current observational data.
This paper proposes that supermassive primordial black holes, formed via a catalyzed dark sector phase transition involving domain walls, serve as the seeds for JWST's observed "Little Red Dots" while simultaneously generating a testable ultra-low-frequency gravitational wave background.
This paper proposes a bipartite solution to the primordial lithium problem involving two sequential late decays—a majoron into neutrinos that reduces lithium but overproduces deuterium, followed by an axion-like particle into photons that photodissociates the excess deuterium while further depleting lithium—demonstrating a viable mechanism to resolve the lithium discrepancy without violating current deuterium constraints.
This paper proposes a model-independent method for directly measuring the production fractions of and mesons at the resonance by counting single- and double-inclusive charmed mesons, demonstrating that world-average precision can be achieved without relying on underlying theoretical assumptions.
This paper proposes that dark particles with lepton-flavor-violating couplings to the tau lepton can trigger decay cascades resulting in rare, high-multiplicity neutrinoless tau decays (such as or ) that dominate over traditional three-body signatures and offer new experimental search channels across various dark sector models.
This paper presents an analytical computation of angular phase-space integrals with three and four denominators using dimensional regularisation and the Mellin-Barnes representation, expressing the results in terms of Goncharov polylogarithms and deriving recursion relations to facilitate the solution of full phase-space integrals.
This paper presents a comprehensive simulation of primordial black hole (PBH) cluster evolution using the Smoluchowski coagulation equation and Monte Carlo methods to model merger dynamics with and without mass segregation, thereby determining runaway timescales and mass population evolution to explain high-redshift supermassive black holes observed by JWST.
