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 derives terrestrial constraints on Majorana bulk neutrinos within the Dark Dimension scenario by analyzing their mass spectrum and mixing, demonstrating that KATRIN beta-decay data provides the strongest limits on Yukawa couplings while the Kaluza-Klein tower effectively screens neutrinoless double beta decay signals.
This paper introduces a novel numerical method combining the Witten-Feynman parameterization with a "reduced Schwinger" technique to analytically resolve oscillatory subintegrals, thereby enabling the first direct evaluation of complete one-loop cosmological bispectrum signals for general masses and momenta and facilitating their comparison with CMB data.
This paper investigates the collider phenomenology of a topological portal connecting QCD to pseudo-Nambu-Goldstone dark matter by constructing a weakly coupled ultraviolet completion with a vector mediator, which enables the calculation of thermal coannihilation and provides testable predictions for LHC, LEP, bottomonium, and future FCC-ee experiments.
This paper clarifies the origin and computation of Sommerfeld enhancement and bound states in singular potentials using non-relativistic effective field theory and position-space regularization, demonstrating that while weakly coupled UV-complete theories yield no enhancement, derivatively coupled pseudoscalar mediators can generate significant enhancement through the interplay of large hierarchies between the cutoff scale and dark matter mass.
This paper extends the analysis of primordial black hole runaway growth to the reheating era, deriving analytical solutions that reveal how reheating dynamics and formation time modify critical conditions for runaway absorption and establish a composition law for combining mass-growth mechanisms across cosmological eras.
This paper introduces a phenomenological framework for fully-heavy tetraquark spectroscopy using a colour-Casimir adjacency matrix approach, which corrects the mass ordering flaws of previous Laplacian-based models and predicts an all-bottom ground state at 18.7–18.9 GeV while highlighting the necessity of long-range molecular dynamics to explain the under-binding of the state.
This paper proposes a generalized chiral model featuring inelastic scalar dark matter to explain the 248 keV nuclear recoil event observed by the LZ collaboration, where a small mass splitting between nearly degenerate states suppresses low-velocity scattering while enhancing high-energy interactions consistent with current experimental constraints and relic abundance.
This paper demonstrates that enforcing -channel unitarity in high-energy elastic $pp$ scattering models significantly increases the extracted dynamical gluon mass scale from approximately 300–420 MeV to 750–1100 MeV, revealing that the physical infrared scale is a unitarity-dressed quantity determined jointly by the nonperturbative gluon propagator and multiple-exchange dynamics.
This paper demonstrates that in Metric-Affine Gravity, non-minimal couplings to torsion and non-metricity terms (specifically Holst and Nieh-Yan) modify axionic wormhole dynamics to enhance the Euclidean action, thereby alleviating the axion quality problem while remaining compatible with inflationary constraints.
This paper presents a comprehensive lattice QCD study using RBC/UKQCD ensembles to determine the masses, decay constants, and compositeness parameters of positive- and negative-parity charm-strange and bottom-strange mesons, providing the first lattice results for and and confirming that the positive-parity states are predominantly molecular in nature.
