Abstract

The supersymmetric contributions to the K _L −K _S mass difference makes the previously obtained bounds on the right-handed scale (M _R >1.6 TeV) much weaker. This raises the interesting possibility that the left-right model could be tested as an alternative to SU _L (2)⊗U(1) at low energies. Also we find that to demand that the supersymmetric contribution to the K _L −K _S mass difference be less than 3.5×10 ⁻¹⁵ GeV requires that scalar-quark masses be more than 400 GeV.
