文摘
A search for pair-produced bottom-like quarks in pp collisions at is conducted with the CMS experiment at the LHC. The decay b→tW is considered in this search. The process can be identified by the distinctive signature of trileptons and same-sign dileptons. With a data sample corresponding to an integrated luminosity of 34 pb−1, no excess above the standard model background predictions is observed and a b quark with a mass between 255 and 361 GeV/c2 is excluded at the 95 % confidence level.
