Improved determination of the D → K−π+π+π− coherence factor and associated hadronic parameters from a combination of e+e-→ψ(3770)→cc̄ and pp→cc̄X data

Measurements of the coherence factor RK3π, 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 superpositio...
