Dear Colleagues, The Chamonix summary is a very important paper and we have to be serious. How can we claim that objects which are formed in the early time of the system like charmonium states cannot tell anything about QGP formation while strange particles and particularly pions which are formed in earlier stages of the system are good probes! The idea that j/psi SUPPRESSION tells nothing about the QGP formation is based on the so-called psi-suppression behaviour similar to the pion behaviour. This is wrong. This result does not come from NA50 and is based on wrong arguments. It essentially comes from the assumption that Drell-Yann changes like ET**4/3 while if we look at DY/ET**4/3, the ratio decreases from about 1.3 to .7 (a.u.) from 35 to 60 geV and stays more or less constant after (this information is completely preliminary and has not been shown by NA50). This tends to flatten completely the behaviour of the so-called multiplicity of psi/pion which is extracted wrongly from the psi/DY ratio. This kind of information should be given only by the collaborations themselves who can provide the correct results. The rest is misinformation! Please can you forward this mail ( and if possible my previous one) to the other participants of the meeting. It is important to propagate only correct informations. As far as the errors of the psi/DY_th (coming from the minimum bias spectrum) are concerned, the statistical errors are about 6 times smaller than the errors of psi/DY_exp and the systematic errors are smaller. (we are dealing with ratios and the only systematic error is related to the normalization of the spectra. This is very small and does not change the shape). I apologize for this very violent reaction! Best regards, Claudie
