rev.415 Chi square distribution HES , CH2 HKS , CH2 • Scan • htrkchi2<X , etrkchi2<300 • htrkchi2<300 , etrkchi2<X HKS , 52Cr HES , 52Cr
Event num. ratio χ2 distribution is wide for HKS! HKS tracking is not good . (HES tracking is better . ) bound- and QF- Λ
multiplicity vs. chi-square 52Cr rev.415 χ2 cut select single hit
multiplicity vs. chi-square CH2 rev.415 χ2 cut select single hit
Multiplicity vs. Missing mass for 52Cr target selected kaon
summary and to do • summary • chi-square (rev.415) • number of event ratio HES tracking is better than HKS. • multiplicity vs. chi-square χ2 cut -> single hits can be selected • multiplicity vs. MM for 52Cr target • to do • H2O target (chi-square , multiplicity) • read tracking code • golden data to analyzer [d.doi] • Fortran - c++
