10:30   Selemon reported on his blastwave work.

Present: Steve, JH, Chellis, Ramiro, Selemon and Michael

Hydro+Cascade: Steve
====================
Steve presented his comparisions of AuAu and CuCu flow results to the  
Hydro+cascade model. The model is working pretty well but he hopes to  
double his statistics. There was a sense at the meeting that he  
should keep the kaons in his AuAu plots. The CuCu result does not  
have so many statistics and also needs careful run by run checking.  
JH suggested that we try to compare min-bias AuAu with min bias CuCu.  
Steve will try this.

P/pi proceedings: Pawel
=======================
Pawel posted his proceedings on the agenda above.Please take a look  
at them before he has to submit them to QM09 in 2 weeks.


d/p paper draft: Michael
========================
Flemming and Casper have produced new spectra in the forward region  
and so extended the Pt reach of the coalesence analysis. The main  
result of the paper is that B2 which is inversely proportional to  
volume of homogeniety seems very consistent with HBT at central  
rapidity and shows almost now rapidity dependence. This is in  
contrast to the phase space density which rises at rapidity 3. In  
this framework it appears that we have very little rapidity  
dependence of the freeze-out temperature but that the chemical  
potential is rising with rapidity.

There is still some work to do on the references and updates of fits  
but Michael would like to have a paper committee look at it.


Thought on Blastwave at forward rapidty: Selemon
=================================================

Selemon has been thinking about fitting the blastwave results to our  
forward rapidity data. One conceptual issue is that the formula  
integrates over all rapidities. (This gives the modified Bessel  
function). He is thinking of modifiying this by doing the integral  
numerically from y=2-4.
He hopes to have a draft of his CuCu paper next week.
