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.

Using the full ANTARES dataset from 2007 to 2022, this study found no significant evidence for dark matter annihilation in the Sun, thereby establishing improved upper limits on WIMP-proton interaction cross sections for masses between 35 GeV and 10 TeV that are consistent with other direct and indirect dark matter searches.
This paper proposes that the nuclear-recoil candidate observed by the LUX-ZEPLIN experiment near 248 keV can be explained by endothermic upscattering of dark matter particles boosted by the decay of a long-lived, massive parent particle, providing a specific benchmark model that links the parent's mass and lifetime to the observed signal.
This paper proposes that the single nuclear-recoil candidate observed by the LUX-ZEPLIN (LZ) experiment at approximately 248 keV originates from the exothermic downscattering of a GeV-scale dark matter state, which is continuously replenished by the decay of a long-lived parent particle, thereby predicting a corresponding signal in argon detectors and constraining the model's photon coupling parameters.
This paper presents the first fully analytic calculation of the four-loop pure-singlet contribution to the quark-to-quark splitting function in perturbative QCD, thereby completing the full splitting function at this order and providing precise numerical representations for parton evolution.
This paper demonstrates that inflationary models with a large number of fields () generically produce almost-local cosmological collider signals in the bispectrum squeezed limit, as extreme value statistics and random-matrix universality drive the scaling dimensions of field mixings toward the unitarity boundary, transforming what would be a fine-tuned signal for few fields into a robust prediction for many.
This paper calculates the decay rate of a negatively charged kaon bound to a light nucleus decaying into pions by employing a subtraction method to overcome slow partial-wave convergence and deriving a small- expansion that agrees with all-orders numerical results.
This paper initiates a systematic study of neutrinoless muon-to-positron conversion by constructing pion-pole-improved nuclear multipoles for local dimension-nine operators, deriving exact two-body nuclear tensors that account for unequal momentum transfers and form-factor arguments, and specializing the results for transitions to facilitate direct contraction with charge-changing two-body transition densities.
This paper demonstrates that a Bayesian-inference-improved CUJET model, which extracts strong coupling and chromo-magnetic monopole fractions from light-hadron data, successfully describes high- heavy-flavor observables and supports a universal description of energy loss driven by chromo-magnetic degrees of freedom near the QCD confinement transition.
By analyzing merged BES and BESIII data on cross-sections, this study demonstrates with 8 statistical significance that the subthreshold pole markedly influences the process by altering the shapes, positions, and widths of seven resonances through interference with the continuum.
This paper presents the derivation of one-loop helicity amplitudes for vector-boson-fusion Higgs-boson production to higher orders in the dimensional regulator using spinor-helicity techniques and -factorised differential equations, providing essential inputs for future exact NNLO QCD computations.
