Search for heavy Majorana neutrinos in μ±μ± + jets events in proton-proton collisions at s=8 TeV
(2015-07-02)
A search is performed for heavy Majorana neutrinos (N) using an event signature defined by two muons of the same charge and two jets (μ±μ±jj). The data correspond to an integrated luminosity of 19.7 fb-1 of proton-proton ...

Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at √s=8 TeV and decaying to μ+μ- are presented as a function of the transverse momentum and rapidity of ...
Search for neutral MSSM Higgs bosons decaying to a pair of tau leptons in pp collisions
(2014-10-28)
A search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The ...
Search for massive resonances in dijet systems containing jets tagged as W or Z boson decays in pp collisions at √s = 8 TeV
(2014-08-29)
A search is reported for massive resonances decaying into a quark and a vector boson (W or Z), or two vector bosons (WW, WZ, or ZZ). The analysis is performed on an inclusive sample of multijet events corresponding to an ...
Search for top-squark pairs decaying into Higgs or Z bosons in pp collisions at √s=8 TeV

collected in 2012 ...
Measurement of the W boson helicity in events with a single reconstructed top quark in pp collisions at √s = 8 TeV
(2015-01-12)
A measurement of the W boson helicity is presented, where the W boson
originates from the decay of a top quark produced in pp collisions. The event selection,
optimized for reconstructing a single top quark in the final ...
Searches for supersymmetry using the MT2 variable in hadronic events produced in pp collisions at 8 TeV
(2015-05-15)
Searches for supersymmetry (SUSY) are performed using a sample of hadronic events produced in 8 TeV pp collisions at the CERN LHC. The searches are based on the M T2 variable, which is a measure of the transverse momentum ...
