  Higher-order QCD predictions are used to extract the top quark mass, both in
the pole and in the $\bar{\mathrm{MS}}$ scheme, from the top quark pair
production cross section measured in the dilepton final state. The analysed
dataset corresponds to an integrated luminosity of 1.14 fb$^{-1}$ collected by
the CMS experiment in 2011 in proton-proton collisions at $\sqrt{s} = 7$ TeV.
