MC request for Lb->LcDspipi

This is the MC production request for

Λb0→Λc+Ds−π+π−\Lambda_b^0\to\Lambda_c^+D_s^-\pi^+\pi^-Λb0​→Λc+​Ds−​π+π−

decay. Two decfiles with difference generator-level cuts on

m(Λcππ)m(\Lambda_c\pi\pi)m(Λc​ππ)

are required since the phase-space distribution shows a significant decrease in the low mass region.

The latest DECFILES release should be used.
