Azimuthal Anisotropy
and the QGP
Reasons why I love
azimuthal anisotropy
Sensitivity to the early stage
Key1; reliable R.P. determination
Key2; PID  with TOF & Aerogel
What we expected before RHIC
Surprise !
Large azimuthal anisotropy
Failure of hadronic scenarios
 v2 vs. Eccentricity
 v2 with particle identification
Mass Ordering in single spectra
Other surprise; baryon dominance
Quark recombination model (RECO)
Proton dominance by RECO
V2 from RECO
Quark number scaling observed!
Mass ordering of quarks?
Study of electron for charm
Charm v2 from electrons
Charm seems to flow!
Study of direct photon
