Using eþe− annihilation data corresponding to an integrated luminosity of 2.93 fb−1 taken at a center-of- mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the branching fractions of the inclusive decays D0 → πþπþπ−X and Dþ → πþπþπ−X, where pions from K0S decays have been excluded from the πþπþπ− system and X denotes any possible particle combination. The branching fractions of D0ðDþÞ → πþπþπ−X are determined to be BðD0 → πþπþπ−XÞ 1⁄4 ð17.60 0.11 0.22Þ% and BðDþ → πþπþπ−XÞ 1⁄4 ð15.25 0.09 0.18Þ%, where the first uncertainties are statistical and the second systematic.

Abstract
Using eþe− annihilation data corresponding to an integrated luminosity of 2.93 fb−1 taken at a center-of- mass energy of 3.773 GeV with the BESIII detector, we report the first measurements of the branching fractions of the inclusive decays D0 → πþπþπ−X and Dþ → πþπþπ−X, where pions from K0S decays have been excluded from the πþπþπ− system and X denotes any possible particle combination. The branching fractions of D0ðDþÞ → πþπþπ−X are determined to be BðD0 → πþπþπ−XÞ 1⁄4 ð17.60 0.11 0.22Þ% and BðDþ → πþπþπ−XÞ 1⁄4 ð15.25 0.09 0.18Þ%, where the first uncertainties are statistical and the second systematic.File in questo prodotto:
