The measurement exploits a data sample equivalent to an integrated luminosity of 2.93 fb(-1), collected by the BESIII detector in e(+)e(-) collisions corresponding to the mass of the psi(3770) resonance. The strong-phase difference is an essential input to the determination of the Cabibbo-Kobayashi-Maskawa (CKM) angle gamma/phi(3) through the decay B- -> DK-, where D can be either a D-0 or a (D) over bar (0) decaying to (KS,LK+K-)-K-0. This is the most precise measurement to date of the strong-phase difference in these decays.eninfo:eu-repo/semantics/openAccessMonte-CarloCp ViolationImproved model-independent determination of the strong-phase difference between D-0 and (D)over-bar(0) -> (KS,LK+)-K-0 K- decaysArticle2-s2.0-8509613914110.1103/PhysRevD.102.052008Q1WOS:000573779800001
