Abstract

Measurements of the coherence factor R_K3π, the average strong-phase difference δDK3π and mean amplitude ratio rDK3π for the decay D→K^-π⁺π⁺π^- are presented. These parameters are important inputs to the determination of the unitarity triangle angle γ in B^-→DK^- decays, where D designates a superposition of D⁰ and D-0 mesons decaying to a common final state. The results are based on a combined fit to observables obtained from a re-analysis of the CLEO-c ψ(3770) data set and those measured in a D0D-0 mixing study performed by the LHCb Collaboration.
