09:30 p + p stopping again revisited Kris Hagel


Kris has been running Pythia to estimate the neutron distribution.  
The default tune and the 320 tune have opposite trends for  
net_neutron/net_proton. Tune 320 seems more reasonable. For example  
it seems to agree with the measurement of net_lambda/net_proton. Plan  
to use this rapidity dependence n/p and lambda/p to get rapidity  
dependent correction factors to make a net-baryon distribution.

JH Asks that Kris count net baryons in Pythia.

ToDo>> Kris will check net baryons in Pythia tune 320

Flemming commented that the energy dependence of the 300 level tunes  
is much better since they incorporate Tevatron, RHIC and low energy  
data. Kris hopes to have time next week and Flemming in mid-november.

K/pi paper: BNL will study the latest version on monday and prepare  
it for publication in PLB.


Steve says that the worst of the semester was over so he hopes to get  
back to V2 soon. We haven't heard from Selemon, presumably because of  
teaching. JH will produce a draft version of the spin paper soon.  
Michael and Casper chugging along on d/p. We should probably submit  
to PRC.
