  Most of the models of jet quenching generally assumes that a jet always
travels in a straight eikonal path, which is indeed true for sufficiently hard
jet but may not be a good one for moderate and low momentum jet. In this
article an attempt has been made to relax part of this approximation for 2 -->
3 processes and found a (15-20)% suppression in the differential cross-section
for moderately hard jets because of the noneikonal effects. In particular, for
the process qq' --> qq'g in the centre of momentum frame the scattering with an
angle wider than \pm 0.52\pi, is literally forbidden unlike the process gg -->
ggg that allows an angular range \pm \pi. This may have consequence on the
suppression of hadronic spectra at low transverse momenta.
