Measurements of inclusive electron cross section and forward-backward asymmetry of e+e- → cc-bar → e+X
Description
We measured the branching fraction of Br(c → e+X) and the forward-backward asymmetry of charm-quark using 12,969-hadronic events. The corresponding integrated luminosity was 108pb-1 and the averaged center of mass energy was 57.95GeV. The e±s were identified by the time projection chamber and the barrel lead-glass calorimeter. The number of identified c → e+ + X events were 121±17. We obtained preliminary results as Br(c → e+X) = 7.8±1.6% and AFBc = -0.45±0.19. They are consistent with world average (Br(c → e+X) = 9.6%) and the Standard Model prediction (AFBc = -0.47). (author)
