### Description

The CMS Experiment at the LHC is currently observing 7 TeV center of mass energy pp collisions. One of the many beyond the standard model searches being conducted by CMS is for evidence of a fourth generation top-like quark (t'). If this object exists, it is expected to decay as: t' -> W b. In pp collisions the top-like quark would be produced with its anti-quark (pp -> t' tbar' -> W+ b W- bbar). This search looks for this decay where one of the W bosons decays leptonically (W$\to$lepton neutrino) and the other hadronically (W -> \$qq\={ }). This analysis studies two channels: muon+jets and electron+jets. Results from a sample of 684 pb-1 muon+jets and 573pb-1 electrons+jets will be presented.
