Sumario: | We present a review of recent results from the CMS experiment on top quark physics.
CMS performed measurements of top quark mass, charge, and decay properties,
$\mathrm{t\bar{t}}$ and single top quark production cross sections in several
channels, as well as measurements of differential production cross sections
and $\mathrm{t\bar{t}}$ production properties: charge asymmetry, spin correlations
and top quark polarization.
For the first time the cross section ratio
$\sigma_{\,\mathrm{t\bar{t} b\bar{b}}} / \sigma_{\,\mathrm{t\bar{t} jj}} $
and the cross section of $\mathrm{t\bar{t}}$ in association with W and Z bosons
have been measured.
CMS established evidence of the W-associated single top quark production.
Most of the measurements have uncertainties dominated by systematic effects.
All of the results are found to be consistent with the standard model predictions. |
