Pions from in-beam Kaon Decay |
| |
- 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;
|
>

-
- 1: pi --> e nu;
- 2: pi --> mu nu;
- 3: pi --> e nu g;
- 4: pi --> mu nu g;

Run the software giving the modified macro file as input parameter, e.g. on an SL6 machine: |
| | /tracking/verbose 1

- The generation of the
K+ -> pi+pi0, pi+ -> mu+ nu, pi+0 -> gg process is handled in fortran files independent from the NA62MC software. These produce a kdecayggl.txt file containing informations on three final state particles: mu+, gamma, gamma.

- In
src/PrimaryGeneratorAction.cc a new case has been added, in which the kdecayggl.txt file is read and the three input particles are inserted into the NA62 apparatus.
In the macros/StandardRun.mac file this option can be selected with /beam/SetBeam PionDecayTest.
The handling of the new parameter has been implemented in src/PrimaryGeneratorMessenger.cc.
