Overview

• Lattice data hint toward lighter sigma
• If sigma mass moves Walecka cancellation is
  violated and much stronger NN and rhoN potentials
• When m(sigma) crosses 2m(pion)gtresonance
  ReV(pions) gets repulsive
• Should affect N and pi flows in opposite
  directions
• Is it what is happening
• at 40 GeV?

• sQGP
• New hydro phenomenon gt Conical flow
• many mesons survive at TgtTc
• plus hundreds of exotic colored binary states.
