Study of tracking efficiency and its systematic uncertainty from J/ψ → pp̅π+π− at BESIII*

Wen-Long Yuan; Xiao-Cong Ai; X. B. Ji; Shen-Jian Chen; Yao Zhang; L. H. Wu; Liang-Liang Wang; Ye Yuan

Based on J/ψ events collected with the BESIII detector,with corresponding Monte Carlo samples,the tracking efficiency and its systematic uncertainty are studied using a control sample of J/ψ→ppπ~+π~-.Validation methods and different factors influencing the tracking efficiency are presented in detail.The tracking efficiency and its systematic uncertainty for protons and pions with the transverse momentum and polar angle dependence are also discussed.Based on J/ψ events collected with the BESIII detector, with corresponding Monte Carlo samples, the tracking efficiency and its systematic uncertainty are studied using a control sample of J/ψ → ppπ+π−.
