Search for fractionally charged particles in proton-proton collisions at = 13 TeV
arXiv:2402.09932 · doi:10.1103/PhysRevLett.134.131802
Abstract
A search is presented for fractionally charged particles with charge below 1, using their small energy loss in the tracking detector as a key variable to observe a signal. The analyzed data set corresponds to an integrated luminosity of 138 fb of proton-proton collisions collected at = 13 TeV in 2016-2018 at the CERN LHC. This is the first search at the LHC for new particles with charges between 3 and 0.9, including an extension of previous results at a charge of 23. Masses up to 640 GeV and charges as low as 3 are excluded at 95% confidence level. These are the most stringent limits to date for the considered Drell-Yan-like production mode.
