Branching ratios and properties of D-meson decays.

Properties of D mesons produced in the photo-production experiment NA 14/2 at CERN are reported. The following ratios of branching fractions were measured:. The D→ K π π π decay was analysed and the contribution of resonant subprocesses found consistent with 1 ρ and 0.23 $$\bar K$$ per event. The angular distributions of D→ $$\bar K$$ showed parity violation and destructive interference between S- and D-waves. From a Dalitz-plot analysis of the decay D→ K π π the contribution from the quasi two-body decay D→ $$\bar K$$ π was measured to be 0.14±0.04±0.04. [ABSTRACT FROM AUTHOR]
