Detailed Description

An observable class for the requirement of perturbative unitarity at next-to-leading order.

Author: HEPfit Collaboration

Copyright: GNU General Public License

This class is used to require NLO unitarity for all the tree level scalar-scalar scattering amplitudes. The eigenvalues of the S-matrix can be found in ?. They should be smaller than ? in magnitude to preserve the unitarity of the S-matrix.
