Abstract:

A measurement of the top quark mass from top quark pair (

\mathrm{t\bar{t}}

) events produced in association with additional hard jets is performed in pp collisions at

\sqrt{s}=8

TeV with the CMS detector using data recorded in 2012, corresponding to an integrated luminosity of 19.7 fb

^{-1}

. The mass is extracted from the normalised invariant mass distribution of the

\mathrm{t\bar{t}}\text{+jet}

system at reconstruction level as well as from the related normalised differential cross section. Both measurements are performed in the dileptonic decay channels (

\mathrm{e^+e^-}

,

\mu^+\mu^-

and

\mathrm{e^{\pm}}\mu^{\pm}

) of the

\mathrm{t\bar{t}}

quark pairs.
