> Dear Tom, Mark, Tim and Flemming:

> I am pleased to announce that PHENIX intends to submit in one week's time
to
> Physical Review Letters a new paper on correlations of charged hadrons
with
> identified trigger particles. You may recall that such correlations have
> important implications for recombination models. The title and abstract
are

>
> Abstract:
>
> Two particle correlations between identified meson and baryon trigger
> particles with $2.5 < p_T < 4.0$ GeV/$c$ and lower $p_T$ charged hadrons
> have been measured at midrapidity by the PHENIX experiment at RHIC in p+p,
> d+Au and Au+Au collisions at $\sqrt{s_{NN}}$=200 GeV.  The probability of
> finding a hadron near in azimuthal angle to the trigger particle is almost
> identical for leading mesons and baryons for non-central Au+Au. The yield
> for both trigger baryons and mesons is significantly higher in Au+Au than
in
> p+p and d+Au, except for trigger baryons in central
> collisions. The baryon excess is likely to arise predominantly from hard
> scattering processes.
