The STAR experiment has now reported two interesting
results on long range correlations
in rapidity. One of the experimental observation
is from a correlation study in azimthal angle and
pseudorapidity for produced charged hadrons with
respect to a particle with larger transverse momentum. Such
studies revealed a jet-like
correlation at small pair phase space separation
(in azimuth and pseudorapidity - near side) which
seems to be unmodified in central Au+Au
collisions relative to d+Au and a significant
correlated yield in central Au+Au collisions at
large pair separation in pseudorapidity (the
RIDGE). The ridge is observed in Au+Au collisions
and not observed in d+Au collisions (See figures).
