Dear ROOTers,
I am facing the following problem, I declare a pointer to a TLorentzVector as:
TLorentzVector *V = 0x0;
and would like to instantiate V with the TParticle::Momentum() method. Suppose I have a TParticle *particle already initialize, I tried the instruction:
particle->Momentum( *V ) but it failed ???
What do I miss?
Many thanks
R
