Abstract
We propose a simple Glauber-type mechanism for the suppression of
jet production up to transverse momenta of about 10
GeV/c at
RHIC.
For processes in this kinematic region, the formation time is
smaller than the interval between two successive hard partonic
collisions and the subsequent collision influences the
jet production. The number of jets then roughly scales with the
number of participants. Proportionality to the number of binary
collisions is recovered for very high transverse momenta. The
model
predicts suppression of jet production
in
d + Au collisions at
RHIC.
