Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(American Physical Society, 2018-01)
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance pTmiss in transverse momentum. The data were collected ...
Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at √s=13 TeV
A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at s=13 TeV with the CMS detector at the LHC, corresponding to an ...
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 ...
Observation of Z decays to four leptons with the CMS detector at the LHC
The first observation of the Z boson decaying to four leptons in proton-proton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb-1 at s=7 TeV collected by the CMS detector ...
Identification techniques for highly boosted W bosons that decay into hadrons
In searches for new physics in the energy regime of the LHC, it is becoming increasingly important to distinguish single-jet objects that originate from the merging of the decay products of W bosons produced with high ...
