Description
While several approaches and their implementations for the
efficient calculation of scattering amplitudes within collinear
factorization applied to hadron scattering exist, no automated tool
exist to achieve the same within frameworks of factorization that
allow for the initial-state partons, entering the hard partonic
process, to have non-vanishing transversal momentum components. I
will present a prescription to construct manifestly gauge
invariant tree-level amplitudes with one or two off-shell
initial-state gluons for processes with arbitrary particles in the
final state, and will show that the prescription allows for
calculations that are efficient and easy to automate.
