Js. Hagelin et al., EXACT SUPERSYMMETRIC AMPLITUDE FOR K(0)-(K)OVER-BAR-O AND B(0)-(B)OVER-BAR-O MIXING, Modern physics letters A, 8(29), 1993, pp. 2737-2745
We present the most general supersymmetric amplitude for K0-K0BAR and
B0-B0BAR mixing resulting from gluino box diagrams. We use this amplit
ude to place general constraints on the magnitude of flavor-changing s
quark mass mixings, and compare these constraints with theoretical pre
dictions both in and beyond the Minimal Supersymmetric Standard Model.
