Abstract
We give a simple physical derivation of the
photon emission rate from the weakly coupled quarkgluon
plasma connected with the collinear processes
and . The analysis is based on the
lightcone path integral approach to the induced radiation.
Our results agree with that by Arnold, Moore and Yaffe (AMY) obtained using
the realtime thermal perturbation theory.
It is demonstrated that the solution of the AMY integral equation
is nothing but the timeintegrated Green's function of the
lightcone path integral approach
written in the momentum representation.
