  The electroweak production of single-top quarks in the $t$ channel can be
changed by any deviation from the standard model, it is therefore an excellent
opportunity to search for new physics. In this poster the recent cross-section
measurement performed by the CMS collaboration is presented with the full 2015
dataset of the LHC Run II at a center-of-mass energy of 13 TeV. The cross
section and the top/antitop ratio is extracted using a binned maximum
likelihood fit to the distribution of a multivariate classifier in events
containing one isolated muon in the final state.
