摘要：

At a future Linear Collider one will be able to determine the masses of charginos and neutralinos and their pair production cross sections to high accuracies. We show how systematically including the cross sections in the analysis improves the measurement of the underlying mass parameters, including potential CP violating phases. In addition, we investigate how experimental statistical errors will affect the determination of these parameters. We present a first estimate on the lower limit of observable small phases and on the accuracy in determining large phases. (C) 2000 Elsevier Science B.V. All rights reserved.
