[Brahms-l] lambda/p ratio vs rapidity

      Dear Casper,
                  BRAHMS has found that the strange chemical  
potential m_s = 0.28 +- 0.04 * m_q
Since lambda is like a proton that has an up quark changed to a  
strange quark then lambda/p is proportional to exp (mu_s - mu_q) =  
exp (0.72 mu_q)  or (pbar/p)**0.12

Given the change of pbar/p from 0.75 to 0.23 from y=0 to y=3.1 I find  
that the lambda/proton ratio should decrease by a factor of 0.86+-0.02

The antilambda/antiproton ratio should INCREASE by this factor.

This seems like a reasonable estimate for the overall change in the  
ratio. I will work on the Pt dependence next.
Michael
