Abstract
According to the helicity conservation (HCns) theorem, the sum of the helicities should be conserved, in any 2-to-2 processes in MSSM with R-parity conservation, at high energies, i.e. all amplitudes violating this rule must vanish asymptotically. The realization of HCns in 
, 
is studied, at the one-loop electroweak order, and simple high energy expressions are derived for the nonvanishing helicity conserving (HC) amplitudes. These are very similar to the corresponding expressions for gg → W+W-, ZZ, γZ, γγ derived before. Asymptotic relations among observable unpolarized cross-sections for many such processes are then obtained, some of which may hold at LHC-type energies.
