Dalitz-Plot Efficiency
Reconstruction efficiencies for the doubly Cabibbo-suppressed (DCS)
D -> K+rr decay and the Cabibbo-favored (CF) D0 -> K-r+7 decay
are very similar, since in both cases the same basic decay tree is being reconstructed.
The only significant difference between the CF and DCS decays is the manner in
which they populate the Dalitz plot. In order to account for this difference when
determining final values, a Dalitz-plot efficiency correction is applied to the data.
This correction does not need to be correct on an absolute scale, since in all cases of
interest, final values involve only ratios of DCS values to CF values.
The Dalitz-plot efficiency is evaluated separately for
D*+- D7+, D0 -K +7r0 (5.1)
D*- D07r8 ,0 - K+7-7T (5.2)
