Advanced usage of FlavorKit
This is the approach to be followed by the user who needs an operator or an observable not included in FlavorKit. In case the user is interested in an operator that is not implemented in FlavorKit, he can define his own operators and get analytical results for their coefficients using PreSARAH. Then the output can be passed to SARAH in order to continue with the basic usage. In case the user is interested in an observable that is not implemented in FlavorKit, this can be easily implemented by the addition of a
Fortranfile, with a few lines of code relating the observable to the operators in FlavorKit (implemented by default or added by the user). The
Fortranfiles just have to be put together with a short steering file into a specific directory located in the main SARAH directory. Then one can continue with the basic usage.
Both possibilities are explained here:
- Advanced usage of FlavorKit to define new observables
- Advanced usage of FlavorKit to calculate new Wilson coefficients
