Combination of the CMS top-quark mass measurements from Run 1 of the LHC

A combination of eight measurements of the top-quark mass from the CMS experiment is presented. The combination is based on the analyses of the data recorded during 2010, 2011 and 2012 with a combined integrated luminosity of 25 fb$^{-1}$.

Sumario:A combination of eight measurements of the top-quark mass from the CMS experiment is presented. The combination is based on the analyses of the data recorded during 2010, 2011 and 2012 with a combined integrated luminosity of 25 fb$^{-1}$. It uses the results from the analyses performed in the dilepton, lepton+jets and all-jets decay channels that correspond to the full datasets from each year. The combined result for the top-quark mass is $172.38 \pm 0.10 \text{ (stat.)} \pm 0.65 \text{ (syst.)} ~\rm{GeV}$, which corresponds to a precision of 0.38\%.
