FLUKA: Kaons in FLUKA

[Bob Zwaska <zwaska@mail.utexas.edu>]

Fluka users,

We have been simulating a 120 GeV proton beam incident on a carbon target and
are interested in the hadron production.  We are having trouble interpreting
what is meant by the distinction of neutral Kaons: KAONSHRT, KAONLONG,
KAONZERON, and AKAONZER.  From 5000 incident protons we register currents of
23 KAONLONGs, 0 KAONSHRTs, 2158 KAONZEROs, and 1315 AKAONZERs.  These numbers
represent the particle current through a plane just ahead of our target, so
the K-shorts may have decayed before being counted.  Anyhow, how am I to
interpret these numbers?

In other work we have simply chosen one half of the K0s and anti-K0s to be
K-shorts, and the other K-longs.  Here, however, we are presented with four
types of distinct particles.

Thanks for any help,
