Improvement of the Higgs mass resolution in the ZH -> L+L- b b channel using a Kinematic Fit with constraints

The measurement of the Higgs mass in the H → bb¯ decay suﬀers from low accuracy of b-jet momentum reconstruction. In order to improve the resolution in mbb¯ a least squares kinematic ﬁt was applied in the ZH → l+l−bb¯ channel. In the ﬁt the b-jet momentum vectors are changed such that they are close...
