Description
Helicity amplitudes for high-energy factorization
Abstract: Contrary to collinear factorization, the initial-state partons in high-energy factorization carry non-vanishing transverse momentum components. As a result, it requires hard scattering matrix elements with off-shell initial-state partons. For these, the question of gauge invariance has to be addressed, which will be done in this presentation.
