This web page summarizes the results for the measurement of the D⁺ &rarr &pi^&minus&pi⁺&pi⁺ branching ratio, based upon 193 pb^{&minus 1} of data.
The results have been approved as of August 31, 2006.

We measure:

B(D⁺ &rarr &pi^&minus&pi⁺&pi⁺)/ B(D⁺ &rarr K^&minus&pi⁺&pi⁺) = (3.461 ± 0.038(stat.) ± 0.040(syst.) )%
