Charm HLT2 lines: LcToV0h and LcToV0hhh

Miroslav Saur requested to merge msaur_LcToV0h_V0hhh into charm-thor-hlt2-lines

Prototype of various Hc (Lambda_c+ / Xi_c+) to V0 (KS0, L0) and h (p, K, pi).

List of implemented lines (Lc+ and Xic+ reconstructed together):

    [Lambda_c+ -> (Lambda0 -> p+ pi-) pi+]CC --> moved to the `hyperons`
    [Lambda_c+ -> (Lambda0 -> p+ pi-) K+]CC --> moved to the `hyperons`
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-)]CC
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-) K+ K-]CC
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-) K- pi+]CC
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-) K+ pi-]CC
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-) pi+ pi-]CC
    [Lambda_c+ -> p+ (KS0 -> pi+ pi-) (KS0 -> pi+ pi-)]CC

Both LL and DD modes of L0/KS0 are included as a separate lines. TO DO:

  • study DOCA cuts for N-body combinations (currently based on hyperon lines)
  • general tuning of cuts

Resulting efficiencies based on the Hlt1 filtered minbias MC sample:
