T-odd correlations of polarizations and momenta provide a promising testing ground for new physics beyond the standard model. We estimate the contribution of the minimal supersymmetric extension of the standard model to two such observables: in the production of $t\bar{ t}$, we look for a term proportional to \mbox{ ${ \bf J}_t \cdot ({ \bf p}_q \times { \bf p}_{ t})$}-where { \bf J}$_t$ is the polarization of the $t$ quark and { \bf p} $_{ q,t}$ are the momenta of the initial and final particles-and find that it is of the order of $10^{ -1} \times (\alpha_s/\pi)$. In the production of $W^+W^-$, we look for a term proportional to \mbox{ ${ \bf E}_W \cdot ({ \bf p}_q \times { \bf p}_{ W})({ \bf p}_q \cdot { \bf E}_W)$}-where { \bf E}$_W$ is the transverse polarization of W- to find that it can be as large as $10^{ -1} \times (\alpha_w/\pi)$.
