BRANCHING RATIO MEASUREMENTS AND ISOSPIN ANALYSIS OF DECAYS OF THE D MESON TO TWO PIONS

Other Titles

Abstract

Using 281 pb−1 of data collected with the CLEO-c detector at the ψ(3770) resonance, we measured branching fractions of the Cabibbo-suppressed decays D0→π+π, D0→π0π0, and D+→π+π0. We used these branching fraction measurements to extract the ratio of isospin amplitudes |A2/A0|=0.429±0.018±0.017 and the relative phase δ=(85.5±3.5±4.1) between these amplitudes, where the uncertainties are statistical and systematic, respectively. Our findings are consistent with, and lend support to the recently published official CLEO-c results.
