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.

The POLONAISE experiment conducted the first search for ultraheavy dark matter using a magnetically levitated milligram-scale ferromagnet, setting leading constraints on dark matter-neutron interactions for masses between and and extending the reach of levitated sensing by seven orders of magnitude.
This paper proposes that warped extra dimensions with a low infrared scale could manifest at the intensity frontier through a unique signature involving the production of heavy Kaluza-Klein gravitons, their cascade down a densely spaced tower, and the subsequent macroscopic decay of the lightest mode into photon pairs, offering a distinct alternative to traditional TeV-scale collider searches.
This paper proposes a non-holomorphic modular double seesaw model that successfully links low-energy neutrino oscillation parameters, testable at experiments like DUNE and JUNO, to the generation of the observed baryon asymmetry via thermal leptogenesis.
This paper introduces Certification-Driven Reinforcement Learning (CDRL), a framework that leverages symbolic reasoning to generate certificates of failure and convert them into reusable constraints, thereby significantly improving the efficiency and success rate of discovering valid neutrino flavor models within vast combinatorial hypothesis spaces compared to existing methods.
This paper demonstrates that electroweak loop corrections in type-II seesaw models fix the Higgs triplet mass splitting to a narrow range, which critically determines the branching ratio of the mixed same-sign decay channel and significantly shifts existing experimental exclusion boundaries depending on the quartic coupling .
This paper demonstrates that Nelson-Barr models with a discrete symmetry naturally predict a light, anomaly-free axion-like particle that solves the strong CP problem, offers a viable dark matter candidate via misalignment production, and can be probed through rare meson decays, stellar cooling, and future cosmological observations.
This paper proposes that repulsive interactions mediated by a dark-sector vector portal can stiffen the equation of state for hyperonic compact stars within the modified quark-meson coupling model, thereby resolving the hyperon puzzle and allowing these stars to reach observed two-solar-mass limits while offering new multimessenger tests for dark matter interactions.
This paper presents a systematic study of R-parity violating operators in the MSSM, classifying their collider signatures and evaluating current LHC coverage to reveal substantial sensitivity in the colored sector while identifying significant gaps for wino- and higgsino-like LSPs with -involving couplings and for directly produced slepton LSPs.
This paper demonstrates that a quantum tadpole identified in fuzzy sphere geometry, which induces surface tension and contraction when isolated, necessitates a coupling to gravity that selects a non-singular de Sitter interior and establishes a specific large- relationship between internal de Sitter time and external Schwarzschild time.
This paper investigates how high-energy QCD resummation, specifically including quark-pair effects, significantly reduces the estimated background from gluon-fusion Higgs-plus-quark-pair production in vector-boson-fusion-like regions, thereby refining the understanding of di-Higgs production at the Large Hadron Collider.
