TLorentz Boost from LHE files

Hi

I am trying to do the following
suppose that you have a ttbar process

p p > t t~

and then in another MC run suppose you have the top decays like (run B)

t > l+ vl b
t~ > l- vl~ b~

So, in order to combine runA and runB, you need to boost the top decay product momenta from runB to the top frame in the run A output…

I know I need to use Math::Boost, but given the fact that the output of runA and runB are in LHE file format, is there a way to do this ?

Regards

Alexis

Hi Philippe…

Let me rephrase… How can I make a LorentzBoost of one frame back to the frame of another system using a TLorentzVector for example ?
thanks
