Résumé fourni par la source

Utilizing 7.9 fb − 1 of e + e − collision data taken with the BESIII detector at the center-of-mass energy of 3.773 GeV, we report the measurements of absolute branching fractions of the hadronic decays D 0 → K − 3 π + 2 π − , D 0 → K − 2 π + π − 2 π 0 and D + → K − 3 π + π − π 0 . The D 0 → K − 3 π + 2 π − decay is measured with improved precision, while the latter two decays are observed with statistical significance higher than 5 σ for the first time. The absolute branching fractions of these decays are determined to be B ( D 0 → K − 3 π + 2 π − ) = ( 1.35 ± 0.23 ± 0.08 ) × 10 − 4 , B ( D 0 → K − 2 π + π − 2 π 0 ) = ( 19.0 ± 1.1 ± 1.5 ) × 10 − 4 , and B ( D + → K − 3 π + π − π 0 ) = ( 6.57 ± 0.69 ±
