ASperGe

A C++ package for Automated SPEctRum GEneration

Diagonalization of the mass matrices in general can only be achieved numerically. To automate the diagonalization procedure into FeynRules, a C++ package, ASperGe, has been designed. ASperGe automatically computes the masses and the mixing matrices starting from a Lagrangian in the gauge basis implemented in FeynRules.

To use ASperGe, the user just implements the model in FeynRules and provides the information about the mixing in the model-file as described in the manual. Calling the interface then creates the version of ASperGe dedicated to the model under consideration. The output of ASperGe can be given back to FeynRules. At that point, ASperGe is independent of FeynRules and can be used on its own.
