Minutes of the BRAHMS Phone conference on RdA and particle ratios from pp. 7th November 7, 2003 Present: Ramero, Bjorn, Kris, Ian, JH, Challis and Michael. Summary: There seems to be a general trend that RdAu (and Rcp ) decreases with rapidity. Bjorn and Ramero are consistent at h=3. However discrepancies still exist. Bjorn and Ramero will make sure that they are using the same runs and will check that the runs are of good quality. We will do a momentum cut before making the Pt distributions. Claus has produced results very fast at eta=0 and 1. Unfortunately Bjorn’s RdAu at h=2 is above that of Claus for h=1. Kris is concentrating on understanding some kinks in the Pt dependence of his particle ratios. He is using mass2 cuts that are momentum dependent. However sometimes the mean mass2 is off the book value. He will center his cuts about the actual mean mass2 of the peaks. We will talk again on Tuesday at 10am BNL time. Michael Murray PDF and word versions of the minutes with pictures are attached.
