Abstract
We present a simple and accurate analytical method for calculating the cross section for polarized and unpolarized isolated prompt photon pr oduction in next-to-leading order, taking into account also the next-t o-leading-order fragmentation contribution in the unpolarized case. We demonstrate the good accuracy of our method over a wide range of the isolation parameters and study the effects the isolation cuts have on the cross section at colliders.
