Abstract
T-odd correlations of polarizations and momenta provide a promising te sting ground for new physics beyond the standard model. We estimate th e contribution of the minimal supersymmetric extension of the standard model to two such observables: in the production of ttBAR, we look fo r a term proportional to J(t) . (p(q) X p(t)) - where J(t) is the pola rization of the t quark and p(q,t) are the momenta of the initial and final particles - and find that it is of the order of 10(-1) x (alpha( s)/pi). In the production of W+W-, we look for a term proportional to E(W) . (p(q) X p(W)) (p(q) . E(W)) -where E(W) is the transverse polar ization of W- to find that it can be as large as 10(-1) x (alpha(w)/pi ).
