Improving Measurements of the CKM Phase $\gamma$ Using Charm Factory Results

Abstract

Several authors have proposed methods to measure the phase $\gamma$ of the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle using decays of the type $B\to DK$. We show how to remove uncertainties from these measurements and increase their sensitivity by measuring CP-conserving phases at a charm factory.
