Study of Z boson production in PbPb collisions at √s NN=2.76TeV
(American Physical Society, 2011-05)
A search for Z bosons in the μ+μ- decay channel has been performed in PbPb collisions at √sNN=2.76TeV with the CMS detector at the LHC, in a 7.2μb-1 data sample. The number of opposite-sign muon pairs observed in the ...
Search for a vectorlike quark with charge 2/3 in t+Z events from pp collisions at √s=7TeV
(American Physical Society, 2011-12)
A search for pair-produced heavy vectorlike charge-2/3 quarks, T, in pp collisions at a center-of-mass energy of 7 TeV, is performed with the CMS detector at the LHC. Events consistent with the flavor-changing-neutral-current ...
