Re: FLUKA: Kaons in FLUKA
Probably I can able to give the explanation:
FLUKA considers in different ways neutral Kaons according to their origin:
If kaons0 are coming from the decay of some resonance,
like for instance a phi particle, which can be produced in the
hadronization stage, then they are labelled KAONLONG
and KAONSHRT.
Otherwise, if coming directly from the hadronization chain, they are
labelled KAONZERO and AKAONZER, according to their parton
content. These kaons, during particle
transport, are then treated as a proper combination of KAONLONG and
KAONSHRT in order to have the right decay properties.
>From the point of view of hadronic interactions instead, only KAONZERO and
AKAONZER have meaning. Therefore, if a KAONLONG has to interact with
another hadron it is first decomposed in KAONZERO/AKAONZER
I ask for confirmation to FLUKA authors.
