| Abstract: Results are reported from a search for pair production of new physics resonances decaying into a top quark and another parton. Two specific models, spin-3/2 excited top quark and $R$-parity violating bottom squark pair production, are considered. Data recorded by the CMS experiment at the LHC from proton-proton collisions at $\sqrt{s}=8\;$TeV corresponding toa total integrated luminosity of 19.5 fb${}^{-1}$ are used. The experimental signature in this search is two leptons (e or $\mu$), two jets coming from decays of bottom quarks, and two jets coming from light flavor quarks or gluons. Resonant decay candidates reconstructed from these objects are studied. The observations are consistent with the standard model. Upper limits on the pair production cross section are set for excited top quarks with masses between 300 GeV and 1000$\;$GeV and for bottom squarks with masses between 250 GeV and 600 GeV. Excited top quark (bottom squark) pair production is excluded at the 95\% confidence level between 300$\;$GeV and 703 GeV (250 GeV and 326 GeV). | ||
