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 standard model production of four top quarks in proton-proton collisions at root s=13TeV
(Physics Letters B, 2017)
A search for events containing four top quarks (t (t) over bart (t) over bar) is reported from proton-proton collisions recorded by the CMS experiment at root s = 13 TeV and corresponding to an integrated luminosity of 2.6 ...
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 ...
Differential cross section measurements for the production of a W boson in association with jets in proton-proton collisions at root s=7 TeV
(Physics Letters B, 2015)
Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse ...
Search for lepton-flavour-violating decays of the Higgs boson
(Physics Letters B, 2015)
The first direct search for lepton-flavour-violating decays of the recently discovered Higgs boson (H) is described. The search is performed in the H - GT mu tau(e) and H - GT mu tau(h) channels, where tau(e) and tau(h) ...
Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton-proton collisions at 8 TeV

We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy root s = 8 TeV, corresponding to an integrated ...
Measurement of the t(t)over-bar production cross section in pp collisions at root s=8 TeV in dilepton final states containing one tau lepton
(Physics Letters B, 2014)
The top-quark pair production cross section is measured in final states with one electron or muon and one hadronically decaying tau lepton from the process t (t) over bar - GT (l nu(l))(tau nu(tau))b (b) over bar, where l ...
Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at root s=8 TeV
(Physics Letters B, 2014)
A search for supersymmetry through the direct pair production of top squarks, with Higgs (H) or Z bosons in the decay chain, is performed using a data sample of proton-proton collisions at root s = 8 TeVcollected in 2012 ...
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 ...
Measurements of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) differential cross sections in pp collisions at root s=7 TeV
(Physics Letters B, 2015)
Differential cross sections as a function of transverse momentum p(T) are presented for the production of Upsilon(nS) (n = 1, 2, 3) states decaying into a pair of muons. Data corresponding to an integrated luminosity of ...
