Search for new physics in top quark production in dilepton final states in proton-proton collisions at √s = 13 TeV
A search for new physics in top quark production is performed in proton-proton collisions at 13 TeV. The data set corresponds to an integrated luminosity of 35.9 fb−1 collected in 2016 with the CMS detector. Events with two opposite-sign isolated leptons (electrons or muons), and b quark jets in...

| description | A search for new physics in top quark production is performed in proton-proton collisions at 13 TeV. The
data set corresponds to an integrated luminosity of 35.9 fb−1
collected in 2016 with the CMS detector. Events with two
opposite-sign isolated leptons (electrons or muons), and b
quark jets in the final state are selected. The search is sensitive to new physics in top quark pair production and in
single top quark production in association with a W boson.
No significant deviation from the standard model expectation is observed. Results are interpreted in the framework of
effective field theory and constraints on the relevant effective
couplings are set, one at a time, using a dedicated multivariate analysis. This analysis differs from previous searches for
new physics in the top quark sector by explicitly separating
tW from t¯t events and exploiting the specific sensitivity of
the tW process to new physics. |
