We summarize the extensive work started in [1] according to which total helicity is conserved for any two-to-two process, at root s >> M(SUSY) and fixed angles, in any SUSY extension of SM. Asymptotically the theorem is exact. But it may also have important implications at lower energies root s greater than or similar to M(SUSY). Up to now, these have been investigated to I loop electroweak (EW) order for the processes ug --> dW(+), (d) over tilde (L)(chi) over tilde (+)(i); as well as the 17 gg --> H,H' and the 9 g g --> V H processes, where H,H' denote Higgs or Goldstone bosons, and V = Z, W(+/-).
