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.
This study utilizes simulated High Luminosity LHC data to investigate the angular distribution of high-mass dimuon pairs in the Collins-Soper frame, employing a simplified Einstein-Cartan model to establish 95% confidence level upper limits on the masses of a spin-2 dark neutral gauge boson and the torsion field.
The paper introduces HDSense, a computationally efficient metric that ranks observable sensitivity by balancing information content and redundancy using one-dimensional histograms, enabling the identification of near-optimal parameter-constraining subsets for complex models like hadronization without requiring full likelihood calculations.
This paper generalizes the concept of family anomalies to broken generalized and categorical symmetries, utilizing anomaly inflow and SymTFTs to constrain the renormalization group flows and infrared phases of families of quantum field theories, with specific applications to 4d QCD-like theories deformed by multi-fermion interactions.
