Abstract
Using 20.3 fb−1 of e+e− collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector operating at the BEPCII collider, the branching fractions of three hadronic charm meson decays, D+ → ϕπ+π+π−, D+ → K0SK+π+π−π0, and D+ → K0SK+ω, are measured for the first time to be (0.54 pm 0.19 pm 0.02) × 10−4, (2.51 pm 0.34 pm 0.14) × 10−4, and (2.02 pm 0.35 pm 0.10) × 10−4, respectively. Futhermore, the branching fractions of D+→ K+K−π+π+π− and D+ → K0SK+η are measured with improved precision, yielding values of(0.66 pm 0.11 pm 0.03) × 10−4 and (2.27 pm 0.22 pm 0.05) × 10−4, respectively.File in questo prodotto:
