Abstract

We consider the issue of determining the D0-Dbar0 width difference Delta Gamma_D experimentally. The current situation is reviewed and suggestions for further study are given. We propose a number of D0 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 D0 -> 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.
