Query: Jet-Like Correlations between Forward and Mid-Rapidity   Mid-rapidity azimuthal correlations probe di-jets originating mainly from
gluon-gluon hard-scattering. Measurements of such correlations have revealed
significant (gluon-)jet modification in central Au+Au collisions. Azimuthal
correlations at forward rapidity with a mid-rapidity high-pt hadron, on the
other hand, are sensitive primarily to quark-gluon hard-scattering and may
probe quark-jet modification in nuclear medium. They may be also sensitive to
the Color Glass Condensate by separating d-side and Au-side in d+Au collisions.
We present the first results on correlations of charged hadrons at forward
rapidity in the STAR FTPCs (2.7 < |eta| < 3.9, pt < 2 GeV/c) with high-pt
charged hadrons at mid-rapidity from the main TPC (|eta| < 1, pt > 3 GeV/c).
Preliminary results from pp, d+Au, and Au+Au collisions at 200 GeV are
compared. Implications of the results are discussed.
