CMS Collaboration; Amsler, C; Chiochia, V; Favaro, C; Verzetti, M; Snoek, H; De Visscher, S; Aguiló, E; Otyugova, P; Schmitt, A; Millan, B; Ivova, M; Storey, J (2011). Search for a heavy bottom-like quark in pp collisions at √s = 7 TeV. Physics Letters B, 701(2):204-223.

Abstract

A search for pair-produced bottom-like quarks in pp collisions at sqrt(s) = 7 TeV is conducted with the CMS experiment at the LHC. The decay b' to tW is considered in this search. The b' b'-bar to tW^- t-bar W^+ 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 inverse picobarns, no excess above the standard model background predictions is observed and a b' quark with a mass between 255 and 361 GeV/c^2 is excluded at the 95% confidence level.
