Abstract
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 0.52π, is literally forbidden unlike the process gg --> ggg that allows an angular range \pm π. This may have consequence on the suppression of hadronic spectra at low transverse momenta.
