Asymptotic Helicity Conservation in SUSY

We summarize the extensive work started in [1], according to which total helicity is conserved for any two-to-two process, at sqrt s >> MSUSY and fixed angles, in any SUSY extension of SM. Asymptotically the theorem is exact. But it may also have important implications at lower energies . Up to now, these have been investigated to 1loop electroweak (EW) order for the processes ; as well as the 17 gg HH', and the 9 gg VH processes, where H,H' denote Higgs or Goldstone bosons, and V = Z, W±.
