Top quark mass combinations using the 2010, 2011 and 2012 data

Two combinations of the measurements of the top quark mass from the CMS experiment are presented. These are based on data recorded between 2010 and 2012 and correspond to an integrated luminosity of up to 20 fb$^{-1}$. The first combination uses results obtained using standard analysis techniques in the dilepton, lepton+jets and all-jets channels. This is compared to preliminary measurements using alternative analysis techniques and to a measurement of the top quark pole mass. A second combination is performed using both the standard and alternative measurements. This results in a top quark mass of $173.49 \pm 0.36 \text{ (stat.)} \pm 0.91 \text{ (syst.)} \GeV$, with a total uncertainty of 0.98 GeV.
