We report a measurement of the top-quark mass using events collected by the CDF II detector from pp collisions at square root of s = 1.96 TeV at the Fermilab Tevatron. We calculate a likelihood function for the top-quark mass in events that are consistent with tt --> bl(-)nu(l)bl'+ nu'(l) decays. The likelihood is formed as the convolution of the leading-order matrix element and detector resolution functions. The joint likelihood is the product of likelihoods for each of 33 events collected in 340 pb(-1) of integrated luminosity, yielding a top-quark mass M(t) = 165.2 +/- 6.1(stat) +/- 3.4(syst) GeV/c2. This first application of a matrix-element technique to tt --> bl+ nu(l)bl'- nu(l') decays gives the most precise single measurement of M(t) in dilepton events. Combined with other CDF run II measurements using dilepton events, we measure M(t) = 167.9 +/- 5.2(stat) +/- 3.7(syst) GeV/c2.
我们报告了利用费米实验室Tevatron的CDF II探测器在(\sqrt{s}=1.96)TeV的质子-质子碰撞中收集的事例对顶夸克质量进行的测量。我们针对与(t\bar{t}\to b\ell^-\nu_{\ell}b\ell'^+\nu'{\ell})衰变相符的事例计算了顶夸克质量的似然函数。似然函数由领头阶矩阵元与探测器分辨率函数的卷积构成。联合似然函数是在(340)皮靶(^{-1})的积分亮度下收集的(33)个事例中每个事例似然函数的乘积，得到顶夸克质量(M_t = 165.2 \pm 6.1)（统计）(\pm 3.4)（系统）GeV/(c^2)。矩阵元技术在(t\bar{t}\to b\ell^+\nu{\ell}b\ell'^-\nu'_{\ell})衰变中的首次应用给出了双轻子事例中对(M_t)最精确的单次测量。结合CDF运行II期利用双轻子事例进行的其他测量，我们测得(M_t = 167.9 \pm 5.2)（统计）(\pm 3.7)（系统）GeV/(c^2)。
