介绍了在大型强子对撞机上用ATLAS探测器测定顶夸克质量的几种方法。顶夸克的所有显性衰变通道都可以被探测到。在大多数情况下,测量结果受系统不确定度的支配。已经开发出新的方法来控制那些与探测器有关的问题。结果表明,在1 GeV的水平上,最高质量的总误差是可以实现的。
Several methods for the determination of the mass of the top quark with the ATLAS detector at the LHC are presented. All dominant decay channels of the top quark can be explored. The measurements are in most cases dominated by systematic uncertainties. New methods have been developed to control those related to the detector. The results indicate that a total error on the top mass at the level of 1 GeV should be achievable.
