dc.descriptionThe Standard Model contributions to the processes $γγ\to γγ$, $γZ$ and ZZ at sufficiently high energies, are found to be helicity conserving and almost purely imaginary. This is due to the W-loop contribution, which is much bigger than the fermionic ones at such energies. Thus the structure of these amplitudes acquires an impressive simplicity at high energies. Nothing like this appears in other process like e.g. the the production of a pair of neutral Higgs bosons.
