Hello, I looked at the newly made DSTs and evaluated the particle ratios at mid-rap for the 10% most central events : data set : 90 A/B 350 (only for now) BB vtx < 15cm Cent [0, 10] track vertex consistency : < 3 sigma dZ, dY I tried pol A / polB and polB / polA -> no difference. Results : pi- / pi+ = 1.0 +- 0.01 (stat) no pt dep. K- / K+ = 0.76 +- 0.04 (stat) no pt dep Pb / p = 0.43 +- 0.03 (stat) no pt dep I will continue investigating the data.
