Description
We report a search for contact interactions due to quark and lepton substructure manifest in production of µ+ µ- and e+e- pairs. The search is performed using the full data set recorded by CMS at √s = 8 TeV corresponding to integrated luminosity of 20.6 fb-1 for dimuons and 19.6 fb-1 for dielectrons. The dilepton yields for invariant masses above 300 GeV are found to be consistent with standard model Drell-Yan production. The yields are compared to those predicted by the left-left isoscalar model of contact interactions for the cases of destructive and constructive interference with standard model Drell-Yan production. Lower limits are set on the contact interaction energy scale parameter for the µ+ µ- and e+e- channels separately, and for the channels combined.
