[Rivet] WFinder

[Jon Butterworth]

Thanks both. Point taken on the rapidity cuts for MET. Damn.

On the before/after hadronisation, if you could fully reconstruct a B- 
of c-hadron decay (which I think would be the main problems), I think 
you could tell what it was, hence its mass, hence know the neutrino 
4-momentum in the hadron rest frame?

I know, it makes me uncomfortable too. But "in principle..."

Cheers,
Jon
