v03 DST. Check pizero peak. Used Yasuyuki and Federica’s micro DST. MIP SM-by-SM correction, TOF Run-by-Run correction, and Tower-by-Tower correction were applied in After Burner. It is easy to find pizero Only PbSc Asym < 0.4 p T dependent opening angle cut

v03 DST Check pizero peak. Used Yasuyuki and Federica’s micro DST. MIP SM-by-SM correction, TOF Run-by-Run correction, and Tower-by-Tower correction were applied in After Burner.
It is easy to find pizero • Only PbSc • Asym < 0.4 • pT dependent opening angle cut • ecore correction (already in DST) • MIP S.M. by S.M. correction • Number of event: 520 K • ( the # of event have at least one cluster (ecore>100 MeV)) • BBC-Z within ± 30 cm. • BBC-T within ± 10 ns. • Cut by corrected Time of Flight • Run-by-Run/Tower-by-Tower • We have achieved 770 ps resolution. • Better than August scan (was 1400 ps) (ecore>0.3 GeV)
Overall: Position: 143 MeV Width : 10 MeV Each pT bin: Position: Higher than known Width: Consistent with August scan
