Find particles with 2-body decay channel from input tracks vRTracks with primary vertex PrimVtx:

  1. K0s->pi+ pi-
  2. Lambda->p pi- All particles are put into the Particles array. 3 cuts for each particle are required. First index in the cuts array sets a particle number (see table above), second index - a cut number: cut[0][0] - chi to a primary vertex of a track (sqare root from a normalized on a total error of the track and the vertex distance between the track and the primary vertex), only element cut[0][0] is used to select tracks, all other elements cut[*][0] are not used; cut[*][1] - chi2/ndf of the reconstructed particle; cut[*][2] - z coordinate of the reconstructed particle. cut[*][3] - chi2/ndf of the reconstructed particle fitted to the PV;
