Measurement of the W-boson helicity in top-quark decays from tt̄ production in lepton+jets events in pp collisions at√s = 7 TeV Th
The W-boson helicity fractions in top-quark decays are measured with tt̄ events in the lepton+jets final state, using proton-proton collisions at a centre-of-mass energy of 7TeV, collected in 2011 with the CMS detector at ...
Measurement of the Lambda(0)(b) lifetime in pp collisions at √s=7 TeV
A measurement of the λb 0 lifetime using the decay λb 0-1, was recorded with the CMS experiment at the Large Hadron Collider using triggers that selected dimuon events in the J/ψ mass region. The λb 0 lifetime is measured ...
Search for the standard model Higgs boson produced in association with a top-quark pair in pp collisions at the LHC
A search for the standard model Higgs boson produced in association with a top-quark pair is presented using data samples corresponding to an integrated luminosity of 5.0 fb-1 (5.1 fb-1) collected in pp collisions at the ...
