> Dear Friends:
>
> The PHENIX Collaboration intends to submit in one week's time a PRL on HBT
correlations measured with pi+ and pi- pairs. The data
> were shown in preliminary form at QM02 but are now presented with a more
sophisticated treatment of Coulomb effects. Please find the
> title and abstract below.

> Bose-Einstein correlations of identically charged pion pairs were measured
by the PHENIX
> experiment at mid-rapidity in Au+Au collisions at sqrt{sNN} = 200 GeV. The
Bertsch-Pratt radius
> parameters were determined as a function of the transverse momentum of the
pair and as a function
> of the centrality of the collision. Using the full Coulomb correction, the
ratio Rout/Rside is smaller
> than unity for kT from 0.25 to 1.2 GeV/c and for all measured
centralities. However, using recently
> developed partial Coulomb correction methods, we find that Rout/Rside is
0.8-1.1 for the measured
> kT range, and approximately constant at unity with the number of
participants.
