[Brahms-l] Fw: pt spectra from h-h, h-A and A-A at SPS (NA49 data) (fwd)

Hi
There is current discussion about large y behaviour in d-A(pA) resulting
from last weeks workshop which unfortunately coincided with my many other
activities at RHIC. I enclosed a message from Boris (Kopelovich) and in the
subsequent message a rebute by Dima + repost.

regards
