description |
A measurement is presented of differential cross
sections for t-channel single top quark and antiquark production in proton–proton collisions at a centre-of-mass energy
of 13 TeV by the CMS experiment at the LHC. From a data
set corresponding to an integrated luminosity of 35.9 fb−1,
events containing one muon or electron and two or three jets
are analysed. The cross section is measured as a function of
the top quark transverse momentum (pT), rapidity, and polarisation angle, the charged lepton pT and rapidity, and the pT
of the W boson from the top quark decay. In addition, the
charge ratio is measured differentially as a function of the top
quark, charged lepton, and W boson kinematic observables.
The results are found to be in agreement with standard model
predictions using various next-to-leading-order event generators and sets of parton distribution functions. Additionally,
the spin asymmetry, sensitive to the top quark polarisation, is
determined from the differential distribution of the polarisation angle at parton level to be 0.440 ± 0.070, in agreement
with the standard model prediction. |
