[Brahms-l] Fw: New PHENIX paper on pi0 and inclusive photon v2

FYI



> Dear Wit, Tim, Flemming and Sam:
>
> In one week's time the PHENIX Collaboration will submit to Physical Review
> Letters a manuscript on v2 for identified pi0's and inclusive photons. The
> title and abstract appear below.

implication

collisions

> Abstract: The azimuthal distribution of identified pi0 and inclusive
photons
> has been measured in \sqrt{s_{NN}} = 200 GeV Au+Au collisions with the
> PHENIX experiment at RHIC. The second harmonic parameter, v2, was measured
> to describe the observed anisotropy of the azimuthal distribution. The
> measured inclusive photon v2 is consistent with the expected hadron decay
> and is also consistent with the lack of direct photon signal over the
> measured pT range 1-6 GeV/c. An attempt is made to extract v2 of direct
> photon.
