Abstract
We present a detailed and complete calculation of the neutralino contr ibution to the mass difference Delta m(B0d)/m(Bd0) within the MSSM. We include the complete mixing matrices of the neutralinos and of the sc alar partners of the left and right handed bottom quark. We find that the neutralino contribution is generally small but can be of the same order of the chargino contribution and much larger than that of the gl uino over a small range of m(s), given m(g2) and mu and for tan beta s imilar to 50.
