Neutral d-meson properties in 360 GeV/ cπ−p interactions

Neutral d-meson properties in 360 GeV/ cπ−p interactions

Based on a sample of 22 four-prong D 0/ D 0 decays produced in hydrogen by 360 GeV/ c π −, we present the following new results: mean lifetime τ = (3.5 −0.9 +1.4) x 10 −13 s; production cross section for x F > 0.0, σ = (10.3 ± 3.5) ωb; the D → K ± π ± π + π − branching ratio = (7.1 ± 2.5)%....
