Description

In this paper we present a feasibility study for measuring the combination of the Unitarity Triangle angle 2$β+γ$ with a time dependent Dalitz analysis in $B^0$ decays using $D^- K^0 π^+$ final states following the method proposed in [1]. For this study we build a model for this decay using the latest experimental information and we investigate the possibility of fitting together with 2$β+γ$ all the relevant strong amplitudes and phases of the decay model.
