Describe the bug

There was a problem with void boost(MALorentzVector &p) {} (Line 146 in MABoost.h). The old function does not properly boost the Lorentz vector. Below you can find a fix

void boost(MALorentzVector &p) const
{
MAdouble64 bp = bx_ * p.X() + by_ * p.Y() + bz_ * p.Z();
p.SetX(p.X() - gamma_ * bx_ * p.T() + (gamma_ - 1) * bx_ * bp / b2_);
p.SetY(p.Y() - gamma_ * by_ * p.T() + (gamma_ - 1) * by_ * bp / b2_);
p.SetZ(p.Z() - gamma_ * bz_ * p.T() + (gamma_ - 1) * bz_ * bp / b2_);
p.SetT(gamma_ * (p.T() - bp));
}

Hi @ajueid, could you explain what the problem is?

In the code, there is gamma^2 instead of gamma. Cheers, Benj
