Abstract
Measurements of the coherence factor RK3πRK3π, the average strong-phase difference δDK3π and mean amplitude ratio rDK3π for the decay D→K−π+π+π−D→K−π+π+π− are presented. These parameters are important inputs to the determination of the unitarity triangle angle γ in B−→DK−B−→DK− decays, where D designates a superposition of D0D0 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)ψ(3770) data set and those measured in a D0D¯0 mixing study performed by the LHCb Collaboration.
