CEPC Trk & PID meeting H_recoil Status Report Yuji Li(Fudan university)
Status In this formula, the width of Z/H should be measured as a constant with H invisible events. We use a chi square method to find the best lepton pair. Clear relation between Z boson momenta and H recoil. BKG Inputs: /cefs/higgs/liugeliang/CEPC/202501/Production/4fermions/ /cefs/higgs/liugeliang/CEPC/202501/Production/2fermions/ 2
Irreducible bkgs 4fermions 2fermions
BKG Samples: eeTo(anything)To2l2nu Fitted by exponential 4
BKG Samples: eeTo(anything)To2l2q Fitted by exponential 5
BKG Samples: eeToZZ4L Fitted by polynomial 6
BKG Samples: Zll_isr Fitted by exponential
BKG Combination Lumi: 20(fb-1) xs zz_l0mumu=2*19.38; xs 4mu=15.56; xs sl0mu_down=136.14; xs sl0mu_up=87.39; xs zzorww_l0=221.10; xs ll=5332.71; Fitted by exponential
Summary and plans All the bkg from MC for irreducible bkg has been ready. Muon detector has been constructed in CEPCSW, will update the muon selection in this study. Final fit of H recoil shape is debugging. 9
