Description
We present measurements of the top quark mass in proton-proton
collisions at the LHC at a centre-of-mass energy of 7 TeV using
data collected by the CMS experiment during the year 2011.
Measurements are presented in all possible final states originating
from top-pair production, and the different reconstruction methods
to extract the top quark mass are discussed. Particular emphasis will
be given to the contribution of systematic uncertainties. The results
of the various channels are combined and compared to the world
average. The determination of the top-pair invariant mass is also presented, and the result interpreted in the light of possible new physics signatures in the production of top-quark pairs.
