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 study presents a non-parametric reconstruction of the dark subhalo in the strong-lensing system JVAS B1938+666, revealing a dense kiloparsec-scale core that is better explained by self-interacting dark matter (SIDM) and fuzzy dark matter models than by standard NFW profiles, with SIDM being the favored framework.
This paper identifies a universal reduced-dynamical framework where eliminating intermediate sectors in both light-nuclei formation and cosmological Bose-Einstein condensation generates non-Markovian memory kernels, enabling predictions that the sequential-to-direct hypertriton formation ratio is sensitive to the hadronic stage's expansion history.
This paper demonstrates that both a 100 TeV hadron collider and a 10 TeV muon collider possess the sensitivity to discover new physics up to approximately 6 TeV by probing Higgs coupling deviations that are necessary to restore unitarity in weak boson scattering, with potential corroboration from an intermediate FCC-ee precision program.
This paper demonstrates that suitable quartic couplings in the Pati-Salam model can prevent symmetry restoration at high temperatures, thereby avoiding the thermal production of 't Hooft-Polyakov monopoles and removing associated constraints on the symmetry breaking scale.
This paper constructs a quantum Schwinger-Keldysh effective field theory for diffusive hydrodynamics that enforces fluctuation-dissipation relations via KMS symmetry to reveal intrinsically non-Gaussian noise, ultimately deriving one-loop quantum corrections that generalize hydrodynamic long-time tails to arbitrarily high orders in .
This paper investigates permutation-enforced - mode mixing in triply heavy baryons and within the diquark picture, demonstrating that the Pauli exclusion principle necessitates mixed-mode eigenstates that replace pure Regge trajectories with novel sprouting-branch-like effective radial trajectories exhibiting scaling.
This paper proposes a minimal model where the top quark undergoes a nonstandard cascade decay into a new scalar and a charm quark via a dimension-5 operator mediated by a heavy vectorlike quark, leading to distinctive collider signatures such as and vectorlike quark production events at the LHC.
This paper demonstrates that a recently discovered exact separation of gravitoelectric perturbation equations provides a highly accurate and practical method for computing Kerr-Newman black hole quasinormal modes, yielding results consistent with coupled-system calculations and offering numerical evidence for spin-label isospectrality even in near-extremal configurations.
This paper demonstrates that Standard Model flavor anomalies associated with magnetic monopoles induce a striking phenomenological consequence where electroweak interactions cause scattering processes to violate baryon and lepton number by multiples of three (), even when these quantities are classically conserved, a mechanism explicitly illustrated within Pati-Salam and trinification theories.
This paper resolves the apparent discrepancy between the linear () and quadratic () scaling of photon growth rates in stimulated axion decay by demonstrating that the transition from parametric resonance to kinetic behavior is governed by the coherence properties and momentum dispersion of the axion field.
