|Vz - VpdVz| < 6cm

Tracking and PID cuts:
- nHitsFit > 20 && nHitsFit/nHitsPoss > 0.52                             
- at least one hit in every layer of PXL and IST.
- pT > 1.2 for kaons and pions
- if beta>0 use TOF else use TPC
- Reduce K,pi overlap region by applying rough asymmetric cuts (p>1.3 -2<nSigmaTof_K<3, -3<nSigmaTof_pi<2). //This could be not necessary.
- |nSigmaPion| < 3.0
- |nSigmaKaon| < 2.0

signal counts are calculated by integrated foreground within +/- 2.5sigma - integration of exponetial function within the same mass region.

HFT cuts (Topological cuts) listed as: "pT_Dca_DcaDaughter_costheta"
Scan the cuts as the following:
pT: 0.8 - 1.3, dpt = 0.05
Dca: 0.003 - 0.01, dDca = 0.001
DcaDaughter: 0.003 - 0.01, dDcaDaughter = 0.001
costheta: 0.98 - 0.997, dcostheta = 0.002
