Description
We calculate the classical single-gluon production amplitude in
nucleus--nucleus collisions including the first saturation
correction in one of the nuclei (the projectile) while keeping
multiple-rescattering (saturation) corrections to all orders in the
other nucleus (the target). In our approximation only two nucleons
from the projectile nucleus interact: the single-gluon production
amplitude we calculate is order-$g^3$ and is leading-order in the
atomic number of the projectile, while resumming all order-one
saturation corrections in the target nucleus. Our result is the
first step towards obtaining an analytic expression for the first
projectile saturation correction to the gluon production cross
section in nucleus--nucleus collisions.
