Loops in the gluon emission amplitude: reggeization from the eikonal scattering
- 39 Downloads
It is shown that in the eikonal scattering of a fast quark in the external field loop corrections to the gluon emission amplitude due to virtual softer gluon after renormalization coincide with a correction due to reggeization of the exchanged gluon in the BFKL picture.
