First measurement of the top quark mass\\ in pp collisions at $\sqrt{s}=$7~TeV
We report on the first measurement of the top quark mass ($m_{top}$) in the dilepton decay channel $t\bar{t}\rightarrow(l^{+}\nu_l b)~(l^{-}\bar{\nu}_l \bar{b})$ in pp collisions at $\sqrt{s}=7$~TeV.

| description | We report on the first measurement of the top quark mass ($m_{top}$) in the dilepton decay channel
$t\bar{t}\rightarrow(l^{+}\nu_l b)~(l^{-}\bar{\nu}_l \bar{b})$ in pp collisions at $\sqrt{s}=7$~TeV.
The mass is reconstructed using two numerical methods which rely on the kinematic characteristics of the events:
a full kinematic analysis and an analytical matrix weighting technique.
Both methods use a likelihood fit to derive the mass from the observed data
and the combination of the results yields a measurement of
$m_{\rm top}=175.5\pm4.6(stat)\pm4.6(syst)$~GeV/$c^2$. |
