Study of Hb`b, c`c and gg in the `H channel Jianping Dai (SJTU) 07/07/2015

Physics Motivation To measure the BR of Higgs decay to b, c and gluon in the process of ee−Z(`)H at 250GeV; The BR of Z(`)H is twice as large as the BR of Z(l`l)H;

MC Samples and Cross Sections (fb) `qq backgrounds l`lqq backgrounds l`qq backgrounds

MC Samples and Cross Sections (fb) ZH background: HWW*, ZZ*… l`ll`l backgrounds All the samples are from the full simulation; The signal sample is reconstructed with the newest Arbor, but the backgrounds samples are also used old Arbor; All the signal and backgrounds are normalized to 5ab-1; Because of the lack of the sample, the qq background isn’t considered now;

If selecting a least lepton (electron or muon), the initial events after passing FSClasser is about 25000, the efficiency will be reduced nearly by 85%;
