1 A study of the phase diagram in the domain populated by heavy-ion collisions with the bombarding energy ~ 5 divide 10 GeVnucleon to search
for the mixed phase seems to be a very attractive task
2 The use of the isospin asymmetry as an additional conserving parameter to characterize the created hot and dense system attracts new interest in this problem (critical end-boundary hypersurface )
3 The available theoretical predictions are strongly model dependent giving rather dispersive results There are no lattice QCD predictions for this highly nonpertubative region Much theoretical work should be done and only future experiments may disentangle these models
4 A JINR Nuclotron possibility of accelerating heavy ions to the project energy of 5A GeV and increasing it up to 10A GeV can be realized in two-three years This will enable us to effort a unique opportunity for scanning heavy-ion interactions in energy centrality and isospin asymmetry It seems to be optimal to have the gold and uranium beams in order to scan in isospin asymmetry in both central and semi-central collisions at not so high temperatures

1 A study of the phase diagram in the domain populated by heavy-ion collisions with the bombarding energy ~ 5 divide 10 GeVnucleon to search
for the mixed phase seems to be a very attractive task
2 The use of the isospin asymmetry as an additional conserving parameter to characterize the created hot and dense system attracts new interest in this problem (critical end-boundary hypersurface )
3 The available theoretical predictions are strongly model dependent giving rather dispersive results There are no lattice QCD predictions for this highly nonpertubative region Much theoretical work should be done and only future experiments may disentangle these models
4 A JINR Nuclotron possibility of accelerating heavy ions to the project energy of 5A GeV and increasing it up to 10A GeV can be realized in two-three years This will enable us to effort a unique opportunity for scanning heavy-ion interactions in energy centrality and isospin asymmetry It seems to be optimal to have the gold and uranium beams in order to scan in isospin asymmetry in both central and semi-central collisions at not so high temperatures

NuclotronFAIR GSI
1 A study of the phase diagram in the domain populated by heavy-ion collisions with the bombarding energy ~ 5 divide 10 GeVnucleon to search
for the mixed phase seems to be a very attractive task
2 The use of the isospin asymmetry as an additional conserving parameter to characterize the created hot and dense system attracts new interest in this problem (critical end-boundary hypersurface )
3 The available theoretical predictions are strongly model dependent giving rather dispersive results There are no lattice QCD predictions for this highly nonpertubative region Much theoretical work should be done and only future experiments may disentangle these models
4 A JINR Nuclotron possibility of accelerating heavy ions to the project energy of 5A GeV and increasing it up to 10A GeV can be realized in two-three years This will enable us to effort a unique opportunity for scanning heavy-ion interactions in energy centrality and isospin asymmetry It seems to be optimal to have the gold and uranium beams in order to scan in isospin asymmetry in both central and semi-central collisions at not so high temperatures
Conclusions
We greatly appreciate many useful and valuable discussions with
