Measurements of the branching fractions of the inclusive decays D0(D+)→π+π+π-X

Using e+⁢e- 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 → π+π+π-X and D+ → π+π+π-X, where pions from $K^0_S$ dec...

Zusammenfassung:	Using e+⁢e- 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 → π+π+π-X and D+ → π+π+π-X, where pions from $K^0_S$ decays have been excluded from the → π+π+π- system and X denotes any possible particle combination. The branching fractions of D0⁡(D+) → π+π+π-X are determined to be B⁡(D0 → π+π+π-X) = (17.60 ± 0.11 ± 0.22)% and B(D+ → π+π+π-X) = (15.25 ± 0.09 ± 0.18)%, where the first uncertainties are statistical and the second systematic.
