Dear Ajay,

I think Lambda->GetStartVertex() gives you the true creation vertex of the Lambda, but you probably are looking for the decay vertex of it. For that you should use the GetStartVertex method for one of its true daughters, i.e. the proton or the pion (which both should have the same start vertex as cross check).

Best,
Klaus
