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 √(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 √(s)∝MSUSY. Up to now, these have been investigated to 1loop electroweak (EW) order for the processes ug →dW+,dLχ+i; as well as the 17>>→HH', and the 9 >>→VH processes, where H,H' denote Higgs or Goldstone bosons, and V=Z, W±.
