Hi Deviants, We'd like to take a look a couple of things in the p+p data, in particular we'd like to check the pbar/p ratio to see whether the ultra preliminary BRAHMS result of 0.8 is correct or if the PHENIX 0.6 value is reasonable. We are looking at the DSTs made by Kris (thanks!) I have a couple of questions: 1. Do I recall correctly that only H2 has been calibrated? 2. How does one get a 'reasonable' collision vertex...or is it not possible. I know that the TOF info comes from the added scints at the fronts of the spectrometers, but is it possible to use the inelastic counters to get a vertex? Probably this has been written to the list by someone already and I missed it, if so, please point me to the appropriate email in the archive... Cheers, Ian -------------------------------------------------------------------- | I.G.
