Firstly, let's take a look at the yields from central collisions (b=0-3 fm). To do this, you have to decode RQMD's PID scheme to LUND scheme, and then I go to GEANT scheme (thanks to Dieter, Heng and Roy for getting me going). However, GEANT does not have PID's as far as I know for phi mesons or delta baryons or some others (which ARE still around at the end of the calculation), so I "extended" this scheme a bit. By the way, the LUND scheme (JETSET 6.2) is not what is on the cern pages; I guess it is an old scheme. To find the new one, go to CPC39, 347 (1986). What?-- You don't know what is CPC? Neither did I-- it is Computer Physics Communications.

Anyway, the code runs for 50 fm/c, and plotted in the following pictures on top is the particle yield at the end of the calculation. So, most of the delta's have decayed, but there are a few around still. Also phi's and stuff.

At the bottom panel is shown, for the pions at the end of the calculation, the "nature of the last collision", which could actually be a decay. There are plenty of pions from collisions, strings, "high mass decays" (that's what RQMD says-- I don't know more), and deltas. Even a couple of pions from ropes, and some from cascades and Sigma*'s and etaprime's. (NB: If a pion comes from Delta decay, RQMD does not specify what type of Delta it was, so all are plotted in the Delta++ bin.)

So here are the plots. These yields are the sum of 100 events at b=0-3 fm. The histogram is the results of running RQMD in cascade mode, and the red stars are when the meanfield is on. It can be hard to read the x-axis (which labels the particles), so a postscript version of each is available too.

What do we see? Just a preliminary glance says:
