  • Factorisation scale reliably stored in event record now

New features

  • The minimal invariant mass allowed for any pair of particles in the hard scattering can now be adjusted with the parameter INT_MINSIJ_FACTOR=1.e-12, which will be multiplied with E_CMS^2 to implement the numerical cut-off.
  • Yukawa couplings in the Two-Higgs-Doublet-Model made more flexible
