Determination of the top quark mass from the $t\bar{t}$ cross section measured by CMS at $\sqrt{s}=7$ TeV

Higher-order QCD predictions are used to extract the top quark mass, both in the pole and in the $\overline{\mathrm{M}\mathrm{S}}$ 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.
