Output from the RQMD code at E895 energies
Heng Liu has been running RQMD at LBL for E895 energies with meanfield on and off
(this means toggling switch 23). All other switches were default.
Importantly, Switch 16 was .true., which means that resonances
are not forced to decay at the end of the calculation. This is
good, since otherwise you can get a big spike in the time emission pattern of, say,
pions. When doing HBT, for example, it is important to decay these resonances by
hand (e.g. there is an undecayed eta meson for every 20 piminus at the end of
the calculation)-- this reduces the lambda parameter in HBT.
For a very nice web page about RQMD, see
Heinz Sorge's homepage.
If you are just starting, you should take a look at the yields of
particles for each energy with meanfield on and off.
"Final" pions from RQMD
If you looked at the yields, then you saw lots of things that are still there in RQMD that
will eventually decay into pions.
We have a code to decay those unstable particles by hand to wind up with the final negative
pions. Go here for a discussion.
