Abstract
A search for pair-produced bottom-like quarks in pp collisions at âs=7 TeV is conducted with the CMS experiment at the LHC. The decay b'âtW is considered in this search. The b'b'âtâ¥W-tÌW+ 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. © 2011 CERN.File in questo prodotto:
