Measurement of the Lund plane for light- and beauty-quark jets / LHCb Collaboration
The substructure of jets in quantum chromodynamics (QCD) has garnered significant attention with the advent of infrared- and collinear-safe clustering algorithms and observables. [...]

Measurement of the flux, spatial, angular, and momentum distributions of muons with FASER experiment at the LHC / Keyken, Alex (University of London (GB)) ; Ohashi, Ken (Universitaet Bern (CH)) ; Shamim, Mansoora (CERN) /FASER collaboration
Recent measurements by FASER and SND@LHC experiments have also demonstrated the direct detections of neutrinos at the Large Hadron Collider, while most of the particles arriving at the detectors can be muons. The muons arriving at the FASER detector can either be background sources for analyses or proxies for hadron production at interaction points [...]

First measurement of neutron capture multiplicity in neutrino-oxygen neutral-current quasi-elastic-like interactions using an accelerator neutrino beam / T2K Collaboration
We report the first measurement of neutron capture multiplicity in neutrino-oxygen neutral-current quasi-elastic-like interactions at the gadolinium-loaded Super-Kamiokande detector using the T2K neutrino beam, which has a peak energy of about 0.6 GeV. [...]

Search for millicharged particles in proton-proton collisions at √s = 13.6 TeV / Alcott, S. ; Bhatti, Z, ; Campagnari, C. ; Carrigan, M. ; Citron, M. ; De los Santos, R. ; De Roeck, A. ; Dorofeev, C. ; Du, T. ; Gastal, M. et al.
We report on a search for elementary particles with charges much smaller than the electron charge using a data sample of proton-proton collisions provided by the CERN Large Hadron Collider in 2023-24, corresponding to an integrated luminosity of 124.7/fb at a center-of-mass energy of 13.6 TeV. The analysis presented uses the completed Run 3 milliQan bar detector to set the most stringent constraints to date for particles with charges ≤ 0.24 e and masses ≥.45 GeV..
