2 dec files for Lb2Lcpipimunu, Lc2Lambdapi, with different Lamdba decay z positions

Mengzhen Wang requested to merge mengzhen/add_Lb2Lcpipimunu_Lc2LambdaPi into master

We plan to measure Lambda polarisation, using Lambda reconstructed from TT/LLorDD tracks, with Lambda from Lb->Lcmupipinu, Lc->Lambdapi decay.

This is for Lambda EDT/MDM measurement.

These are the first round of dec files for this study. Generator level selections are loose. We will use the corresponding fully-simulated samples to optimise the selection and T-track reconstruction. After that we will submit new decfiles with improved knowledge.

Several checks are performed by running Gauss and DaVinci using the new decfiles.

  1. The Lambda endvertex Z splitter works fine: 图片图片
  2. momentum cuts on pions not from Lambda decay are added correctly: 图片
  3. "InLHCbAcc" cut added correctly for all pions and muons: 图片
