Generalized gluon currents and applications in QCD.
/ Abstract
We present a recursion relation for a current containing [ital n] off-shell plus an arbitrary number of on-shell gluons. We are able to obtain an exact solution for [ital n]=2 when all of the on-shell gluons have the same helicity, and one of the off-shell gluons is given a generalized'' polarization vector. We then apply this solution to derive an expression for the amplitude for [ital q[bar q]][r arrow][ital q[bar q]gg]...[ital g].
