This case is handled via pichdecays.F. This file is a container for charged pion decays. The routine "pichdecay_manager" is called in kaon decay generators where one ore more charged pions are present in the final state. Two pion decay types are implemented in pich2lnu.F and pich2lnug.F

This case is handled via pichdecays.F. This file is a container for charged pion decays.
The routine pichdecay_manager is called in kaon decay generators where one ore more charged pions are present in the final state (e.g. kch2pipi0.F).
Two pion decay types are implemented in pich2lnu.F and pich2lnug.F, with the possibility to choose the lepton type (electron or muon).

How to run

To run this channel ...
>
>
To run this channel:
  • specify the charged pion decay type in the StandardRun.mac file, at the line with the tag /decay/pichDecay.
    Available charged pion decay types:
    • 0: pi is passed to Geant4;
    • 1: pi-->mu nu;
    • 2: pi-->e nu;
    • 3: pi-->mu nu g;
    • 4: pi-->e nu g;
  • run the software giving the modified macro file as input parameter
    NA62MC macros/StandardRun.mac
