Off-Shell CHY Amplitudes
Published 16 Nov 2015 in hep-th and hep-ph | (1511.05050v2)
Abstract: The Cachazo-He-Yuan (CHY) formula for on-shell scattering amplitudes are extended off-shell. The off-shell amplitudes are M\"obius invariant, and have the same momentum poles as the on-shell amplitudes. The same technique is also used to obtain off-shell massive scalar and vector boson amplitudes.
