Search for heavy, top-like quark pair production in the dilepton final state in pp collisions at ☆

The results of a search for pair production of a heavy, top-like quark,

t^{'}

, in the decay mode

t^{'} {\bar{t}}^{'} \to {bW}^{+} \bar{b} W^{-} \to b ℓ^{+} ν \bar{b} ℓ^{-} \bar{ν}

are presented. The search is performed with a data sample corresponding to an integrated luminosity of

5.0 {fb}^{- 1}

in pp collisions at a center-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC. The observed number of events agrees with the expectation from standard model processes, and no evidence of

t^{'} {\bar{t}}^{'}

production is found. Upper limits on the production cross section as a function of

t^{'}

mass are presented, and

t^{'}

masses below

557 GeV / c^{2}

are excluded at the 95% confidence level.
