Descripción
A measurement of the t\overline{t} production cross section at
√{s}=13 TeV is presented using proton-proton collisions,
corresponding to an integrated luminosity of 2.2 fb-1,
collected with the CMS detector at the LHC. Final states with one
isolated charged lepton (electron or muon) and at least one jet are
selected and categorized according to the accompanying jet multiplicity.
From a likelihood fit to the invariant mass distribution of the isolated
lepton and a jet identified as coming from the hadronization of a bottom
quark, the cross section is measured to be
{σ}_{t\overline{t}}=888±
2,{(stat)}_{-28}^{+26}(syst)± 20(lumi) pb, in agreement with the
standard model prediction. Using the expected dependence of the cross
section on the pole mass of the top quark ( m t), the value
of m t is found to be 170.6 ± 2.7 GeV. [Figure not
