Measurement of the branching ratio of D^{+} &rarr &pi^{&minus}&pi^{+}&pi^{+}
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.) )%

Using the PDG2006 world average branching ration B(D^{+} &rarr K^{&minus}&pi^{+}&pi^{+}) = (9.51 ± 0.34)%,
we find B(D^{+} &rarr &pi^{&minus}&pi^{+}&pi^{+}) = (3.29± 0.11)10^{&minus 3}.
