摘要：

We consider the issue of determining the D-0-(D) over barD(0) width difference Delta Gamma (D) experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D-0 decay modes in addition to those studied in the recent E791. FOCUS and BELLE lifetime determination experiments. Then we address prospects for determining CF-CDS strong phase differences, like delta (K pi) which appears in the CLEO study of D-0 --> K(+)pi (-) transitions. We show how to extract delta (K*pi) with CDS data and furthermore show when D -->- K(L)pi data becomes available that delta (K pi) can also be obtained. (C) 2001 Published by Elsevier Science B.V.
