Abstract

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 $10^{-1} \times (\alpha_w/\pi)$.
