Measurement of top quark polarisation in t-channel single top quark production
(2016-04-01)
A first measurement of the top quark spin asymmetry, sensitive to the top quark polarisation, in t-channel single top quark production is presented. It is based on a sample of pp collisions at a centre-of-mass energy of 8 ...
Search for a massive resonance decaying into a Higgs boson and a W or Z boson in hadronic final states in proton-proton collisions at (Formula presented) = 8 TeV
(2016-02-22)
A search for a massive resonance decaying into a standard-model-like Higgs boson (H) and a W or Z boson is reported. The analysis is performed on a data sample corresponding to an integrated luminosity of 19.7 fb-1, collected ...
Search for supersymmetry in events with soft leptons, low jet multiplicity, and missing transverse energy in proton-proton collisions at s=8 TeV
(2016-08-10)
Results are presented from a search for supersymmetric particles in scenarios with small mass splittings. The data sample corresponds to 19.7 fb-1 of proton-proton collisions recorded by the CMS experiment at s=8 TeV. The ...
Search for heavy Majorana neutrinos in e±e±+ jets and e±µ±+ jets events in proton-proton collisions at √s = 8 TeV
(2016-04-27)
A search is performed for heavy Majorana neutrinos (N) decaying into a W boson and a lepton using the CMS detector at the Large Hadron Collider. A signature of two jets and either two same sign electrons or a same sign ...
Search for the associated production of a Higgs boson with a single top quark in proton-proton collisions at √s= 8 TeV
(2016-06-30)
Abstract: This paper presents the search for the production of a Higgs boson in association with a single top quark (tHq), using data collected in proton-proton collisions at a center-of-mass energy of 8 TeV corresponding ...
Search for R-parity violating decays of a top squark in proton–proton collisions at s=8 TeV
(2016-09-10)
The results of a search for a supersymmetric partner of the top quark (top squark), pair-produced in proton–proton collisions at s=8 TeV, are presented. The search, which focuses on R-parity violating, chargino-mediated ...
