This paper establishes a unified framework for matching KSVZ-like ultraviolet completions to both SMEFT and axion-like particle effective theories, revealing that indirect constraints from precision and flavor observables often dominate over direct ALP searches across large regions of parameter space.
This paper investigates the next-to-leading order electroweak corrections to production induced by dimension-six top-quark operators in the Standard Model Effective Field Theory, demonstrating that indirect sensitivity from virtual corrections at future lepton colliders like LEP3 and FCC-ee can provide competitive constraints on these couplings compared to $ZH$ production and current LEP/LHC data.
This paper analyzes how recent direct detection constraints from DAMIC-M and PandaX limit reheating temperatures in freeze-in dark matter models, demonstrating that viable scenarios with stronger couplings or inflaton-seeded initial abundances can still reproduce the correct relic density while evading current experimental bounds.
Using state-of-the-art 3D simulations, this paper assesses how magnetorotational stellar core collapses contribute to the diffuse supernova neutrino background, finding that they enhance the high-energy spectrum and could significantly accelerate the detection of this background or allow for the measurement of their occurrence fraction in future neutrino observatories.
This paper proposes a method to reconstruct the gluon spatial distribution in high-energy nuclei by measuring the projected momentum transfer distribution perpendicular to the electron scattering plane to mitigate resolution effects and utilizing the angular distribution of vector meson decay products to statistically suppress incoherent backgrounds.
This paper analyzes the synergy between future Tera- factories (such as FCC-ee or CEPC) and non-collider dark matter searches, demonstrating that high-precision electroweak measurements can effectively probe new physics scenarios involving dark matter and a -channel mediator.
This paper presents efficient methods for preparing approximate ground states of SU(3) lattice gauge theory on quantum hardware by refining irrep truncation via energy density, developing perturbation-guided ansatz circuits, and releasing open-source tools for circuit construction and Clebsch-Gordan coefficient calculations.
This paper proposes that the SHIFT@LHC fixed-target concept could enable the first-ever detection of neutrinos in general-purpose LHC detectors (CMS and ATLAS), predicting approximately 10,000 muon-neutrino and 1,000 electron-neutrino interactions from proton-gas collisions to provide unique access to hadron production in the pseudorapidity range of 5 to 8.
This paper revises the Standard Model description of the rare decays by incorporating the previously overlooked cascade contribution, which significantly enhances the predicted decay rate and achieves unprecedented agreement with LHCb data while maintaining consistency with hadronic parameters from analogous four-body decays.
This paper employs effective field theory techniques to derive 1-loop matching conditions and calculate quantum corrections to neutrino mass parameters within the Zee model, demonstrating through four benchmark scenarios the specific conditions under which these corrections must be included in theoretical analyses.
