Chiral Restoration? DCC pion fluctuations… but QCD has more than two flavors
I. DCC with 3 flavors – correlations of Ks0 and K
strange correlations from n DCC “domains”
robust observables, thermal background
II. “conventional” kaon isospin fluctuations
wounded nucleons, HIJING, UrQMD
isospin fluctuations probe models

“2 +1” flavor QCD – transition depends on strange quark masstheory: Pisarski & Wilczek; Gavin, Gocksch & Pisarski; …lattice: Brown et al.; Schmidt, Karsch & Laermann …
SPS + + enhancement explained by many small strange DCC? topological baryon production: Kapusta & Wong; Ellis, Heinz & Kowalski model of chiral symmetry breaking: Kapusta & Srivastava
Kapusta's talkKapusta's talk
Polyakov Loop Condensate model of confinement? many small domains RHIC pT fluctuations: Pisarski & Dumitru K/ enhancement: Scavenius, Dumitru & Lenaghan
consequence:consequence: small strange domains small strange domains kaon fluctuations kaon fluctuations
QCD: chiral symmetry broken by condensate below Tc
condensate for two light flavors:neutral v. charged pion fluctuations
= neutral pion fraction
u, d + strange quark:pion and kaon fluctuations
K = neutral kaon fractionRandrup & Schäffner-Bielich
