MHV amplitudes are not a method. They are amplitudes. Second, if I remember correctly, its not true, except in supersymmetric theories, that the other amplitudes M(all +'s) and M(all + and one -) vanish. At tree level they vanish, but I think even if you look at the original Parke Taylor paper, they write an O(g^4) contribution. Jacob2718 (talk) 07:18, 25 September 2008 (UTC)Reply

Move to Maximally helicity violating (MHV) amplitudes

The acronym for this topic is very unlikely to be known to anyone not working in the field. Johnjbarton (talk) 17:09, 31 December 2024 (UTC)Reply
