Title: Measuring Gamma With B0 to D0 K*0 Decays at Babar

Abstract

We present a feasibility study for a new analysis for extracting the angle of the Unitarity Triangle from the study of the neutral B meson decays. We reconstruct the decay channel B{sup 0} {yields} {bar D}{sup 0}K*{sup 0} with the K*{sup 0} {yields} K{sup +}{pi}{sup -} and the {bar D}{sup 0} {yields} K{sub S}{pi}{sup +}{pi}{sup -} using a D{sup 0} Dalitz analysis technique. The sensitivity to the angle comes from the interference of the b {yields} c and b {yields} u processes contributing to the same final state and by the fact that the B{sup 0}({bar B}{sup 0}) can be unambiguously identified through the sign of electric charge of the kaon from K*{sup 0}({bar K}*{sup 0}) decay. The impact of the result of such analysis is evaluated for the actual BaBar statistics.
