We give numerical examples of the asymmetries and of the cross sections in the Minimal Supersymmetric Standard Model with complex parameters mu, M_1 and A_{tau} for a collider with sqrt{s}=500 GeV. We show that longitudinally polarized electron and positron beams can enhance considerably both the asymmetries and the cross sections.6 pages, 3 figures, contribution to the POWER (polarization at work in energetic reactions) working groupHigh Energy Physics - Phenomenologytext
