Dear Collaborators, For the first publication of BRAHMS, I would like to propose that we write two separate papers (letters) on the particle ratios instead of one which is currently drafted. I believe this is NOT at cost of sacrificing qualities and timing of our first publication(s). - The time to take to submit our first paper should be similar (or shorter) as we currently planed ~ 1 month - By adding another unique result, ratios from MRS at 40/45 degree, we can publish more systematic measurements - We have nice and unique results. We can write two high-quality papers instead of one! - The time gap between two papers can be less than a month. My proposals for the two papers are 1) "Rapidity and centrality dependent pbar/p ratio in Au+Au Collisions at sqrt(s)=130AGeV". and 2) "Transverse-momentum and centrality dependent particle ratios (and spectra) at Mid-Rapidity in Au+Au collisions at sqrt(s)=130AGeV". The first one is to concentrate on pbar/p ratios including data sets from Mid-rapidity at 40/45, 90 degrees and FS at 4 degree: This will give very nice SYSTEMATIC measurements on net-proton distributions. - Systematic: 3 rapidity points instead of two - Unique ratios: 4 degree, 40/45 degree - I think we can produce particle ratios at MRS 40/45 degree in a month. The second paper includes pi-/pi+, K-/K+, pbar/p, K/pi ratios from MRS at 90 degree: - Independent measurements - High quality PID - Wide pt coverage, especially for pbar/p - Ratios at high pt (>1GeV/c) are not yet published - Particle spectra also can be included - This paper can be submitted first. Let me repeat. We have nice and unique results. I believe we can write two nice papers on particle ratios/(spectra) from our two spectrometers in a couple of month. Regards, JH
