  The properties of jets produced in p+p, d+Au and Au+Au collisions at
sqrt{s_NN}=200 GeV are studied using the method of two particle correlations.
The trigger particle is assumed to be a leading particle from a high p_T jet
while the associated particle is assumed to come from either the same jet or
the away jet. From the angular width and yield of the same and away side
correlation peaks, the parameters characterizing the jet properties are
extracted.
