Dear Collaborators, I have received the referee report from PRL for the High pt letter I submitted 2. July, which I enclose below. I have looked up the lecture notes by Kopeliovich (nucl-th/0306044) and have skimmed it, but not read it thoroughly yet. The basic idea is that Kopeliovich says that it is incorrect to use 42mb for the pp cross section and that one should instead use ~30mb . The reason is that, according to him, our trigger counters only cover abs(eta)<3 and therefore miss large rapidity gap events where no particles are produced at midrapidity. How do we respond to this? 1) We use the same as other collaborations, and thus can compare with them. 2) The primary thrust of our paper (in contrast to the other collaborations) is the Rcp, and the pp cross section does not appear here. 3)What was our dAu trigger? IIRC, it was the INEL L+R. I don't know the coverage off the top of my head, but I do believe that it was more forward than eta=3. 4) What other arguments do we have? My suspicion is that the 3 things I list are enough, but I wish we had something a bit more substantive. Best regards, and respond quickly! Ian Bearden 07Jul03 Dr. I.

Acceptance of your paper for publication seems likely, but we first ask you to consider carefully the enclosed comments. Please accompany your resubmittal by a summary of the changes made, and a brief response to any recommendations and criticisms.

Different from all other RHIC collaborations the Brahms results are obtained both a mid-rapidity and forward rapidity (eta = 2.2). These results confirm and complement recent results by PHENIX and STAR: the suppression observed in high p_t hadron production for Au-Au collisions persists to forward rapidities, but is absent in d-Au collisions. For d-Au collisions, rather, a Cronin-type enhancement is observed, casting serious doubts on the interpretation of the Au-Au data in terms of initial state scattering. The paper is well put together and should be published without further delay. I have only the following comment, which the authors may want to consider: the use of 42 mb as inelastic cross section for NN collisions has recently been critized in nucl-th/0306044. Although this is not a published paper, the authors may want to comment.
