Question Weight of G4PrimaryVertex and G4PrimaryParticle 

Forum: Particles
Date: 04 Aug, 2008
From: Niklas <Niklas>

Dear all,

I am working on incorporating variance reduction into a Geant4 program. More specifically, I would like to assign a weight to a particle at the very beginning (and adjusting the weight depending on the initial direction).

What is the difference between

G4PrimaryVertex* vert; vert->SetWeight(w1);

and

G4PrimaryParticle* part; part->SetWeight(w2);

?

And more specifically:

- Are both weights independent? Or does this result in a weight of w=w1*w2?

- Is the weight "transported", i.e. is it being accounted for during calculation of deposited energy?

Thank you!

Niklas

BTW: A very similar question was already asked http://hypernews.slac.stanford.edu:5090/HyperNews/geant4/get/particles/93.html in 2004 but nobody replied.
