  • A bstractA search for compositeness of electrons and muons is presented using a data sample of proton-proton collisions at a center-of-mass energy of s=8$$ \sqrt{s} = 8 $$ TeV collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb−1. Excited leptons (ℓ*) produced via contact interactions in conjunction with a standard model lepton are considered, and a search is made for their gauge decay modes. The decays considered are ℓ* → ℓγ and ℓ* → ℓZ, which… CONTINUE READING
