Hi everybody, This is a write-up of some physics points discussed in Chamonix, which may be useful for the report and later discussion about the future of the SPS program. I tried to write them up in a compact form. 1. There was a very detailed and interesting discussion of all dilepton experiments (of which I am a long-term fan), but the achievements and prospects of hadronic ones came later in the day and were not defined as sharply as they deserve. I think those also belong to ``achievements" section, in some form. Large acceptance of NA49 has allowed new things which was not done before. On top of spectra and HBT, which revealed large radial flow, two new elements emerged: (i) all kind of things related to phi asymmetries, especially rather large elliptic flow; (ii) findings that several observable event-by-event fluctuations look as very regular Gaussian, at least for about 2-3 orders of magnitude measured. The former is not new in general, but new to the SPS energy domain. It is small and not so easy to find, but it is a very instrumental tool to study EARLY SOS, which is one of the central issues of the whole program since it may reveal connection to QCD phase transition. It shows that SOS is definitely VERY SOFT at early stages at SPS because asymmetries are only several percents. (As compared to say 30% from Ollitrault calculations for a simple EOS) It is still about twice what RQMD and several times what VENUS predict: so these string-based models are WAY TOO SOFT in terms of early transverse pressure. The latter is new, and is a big blow to searches for all kind of unusual events, as well as to claims that small number of particles and non-equilibrium effects of all kind would invalidate deterministic approaches based on entropy and thermodynamics. 2. About future program. If the NA50 anomaly survives next run, with its simplified target arrangement (by the way it was not mentioned in Chamonix, I asked Gonin later and he told me about modifications - I think it is a very good step), then the issue of correlation of their signal to other observable would be instrumental, to understand its relation to QGP and the phase transition. Let me try to make this point as simple as possible. Which hadronic observable may show the change of behavior at b about 8 fm in PbPb (or other conditions with similar energy density)? If at this point there is a sudden jump into QGP phase (as Dima and Helmut advocated a couple of years ago, based on bubble formation), then ALL OF THEM including enropy (=multiplicity) should show change. If (as proposed by D.Teaney and myself in recent paper in PLB) J/psi suppression is related to the END of the transition (the ``softest point" of EOS), then one should see a change of behaviour in ELLIPTIC FLOW, a beginning of the rise to be continued at RHIC/LHC. (MAYBE WE ALREADY see the beginning of rise due to pressure of QGP at early time?) If (as proposed by Blaizot/Ollitrault paper and essentially discussed by Helmut at Chamonix) we just find a dissolution of chi's, at some critical density, then one should hardly expect any hadronic observable to react at this point. 3.Practical arrangements are to be discussed by spokesmen of course, but let me inject one more point here. Helmut suggested AB about 10000 (as SnSn) as a step back, in which the suspicious energy density would be at mid-ET. Let me point out that in this case b is about R, which is also the best geometry for elliptic flow measurements. Another option is to keep PbPb, but step down in energy to about 100 GeV, in between 40 GeV (where such conditions are at b=0) and 160. 4. Qualitatively new goal for the SPS program may be a search for a tricritical point (or rather the endpoint of 1-st order transition). It was suggested by Stephanov, Rajagopal and myself recently, and had some resonance among theorists (see e.g. Wilczek's letter in the last Nature). HOW to search was discussed in our paper, but maybe much better ways would be found later. The bottom line is it is THE ONLY really singular point on the phase diagram, where one mode is truly massless. The heat capacity is truly infinite, so one should find a very counterintuitive observations such as: mean Pt (or temperature) fluctuations are nearly absent, or at least significantly less than what random statistics predicts. It would be spectacular to find it! WHERE is it? (Very model dependent and not reliable) estimates done in the mean field approximation. lead to the region in the ballpark of the 40 GeV point. It is not clear how much help a look at ET dependence would provide, but we may still be lucky and find it, if it exists and is down from 40. There is a lot of scepticism about thermodynamical motivations here: but this is a story similar to the endpoint searh of the gas-liquid transition in nuclear matter. Whatever some people may think about it, the peak in multifragmentation was indeed found.
