You can find a large collection of example setups for using SHERPA in various different colliders/processes in the Examples/ directory of the tarball. They are also described in the manual.
- Factorisation scale reliably stored in event record now
- 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^2to implement the numerical cut-off.
- Yukawa couplings in the Two-Higgs-Doublet-Model made more flexible
