Measurement of the ratio B(t - GT Wb)/B(t - GT Wq) in pp collisions at root s=8 TeV
(Physics Letters B, 2014)
The ratio of the top-quark branching fractions R = B(t -- GT Wb)/B(t -- GT Wq), where the denominator includes the sum over all down-type quarks (q = b, s, d), is measured in the t (t) over bar dilepton final state with ...
Search for excited quarks in the gamma plus jet final state in proton-proton collisions at root s=8 TeV
(Physics Letters B, 2014)
A search for excited quarks decaying into the gamma + jet final state is presented. The analysis is based on data corresponding to an integrated luminosity of 19.7 fb(-1) collected by the CMS experiment in proton-proton ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
(Physics Letters B, 2014)
Constraints are presented on the total width of the recently discovered Higgs boson, Gamma(H), using its relative on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays to an ...
Search for pair production of third-generation scalar leptoquarks and top squarks in proton-proton collisions at v root s=8 TeV
(Physics Letters B, 2014)
A search for pair production of third-generation scalar leptoquarks and supersymmetric top quark partners, top squarks, in final states involving tau leptons and bottom quarks is presented. The search uses events from a ...
Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at root s=8 TeV

Search for supersymmetry in pp collisions at root s=8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
(Physics Letters B, 2014)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of 8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least two of which are ...
