Dear Rooters,

    I would like to do a Lorentz transformation to a 4-vector of a particle
going in x-direction. Itīs not clear to me the mechanism to declare the
Lorentz transformation matrix which I need to perform this operation :
/*
TLorentzRotation l;
TLorentzVector v;
  ...
  v=l.VectorMultiplication(v);
  v = l * v;

  v.Transform(l);
  v *= l;
*/

Then how can I put the components of this matrix l ?

Could anyone please give me a suggestion about how to do it?

Thank you very much,
