Precision measurement of the top quark mass in events with two leptons at D0

We present a measurement of the top quark mass in $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV using $t\bar{t}$ events with two leptons ($ee$, $e\mu$ or $\mu\mu$) in the final state. This analysis utilizes an integrated luminosity of 4.3 fb$^{-1}$ collected with the D0 detector at the Fermilab Tevatron collider. We employ a neutrino weighting technique to extract the top mass from 319 dilepton events. To reduce the dominant systematic uncertainties from jet energy calibration, we apply the jet energy corrections determined from a dijet invariant mass using $W\to jj$ decays in $t\bar{t}\to\ell +$jets events. We also apply corrections to jets in Monte Carlo events to replicate the flavor dependence of the jet response in data.
