Abstract

BESIII reports the first observation of the doubly Cabibbo-Suppressed decay D + → K+π +π −π 0 and the first evidence for D + → K+ω using an e +e − collision data sample corresponding to an integrated luminosity of 2.93 fb−1 taken at a center-of-mass energy of 3.773 GeV. The ratio of the branching fractions of D + → K+π +π −π 0 over D + → K−π +π +π 0 is significantly larger than other doubly CabibboSuppressed decays in the charm sector. The CP asymmetry in the separated charge-conjugate branching fractions for D + → K+π +π −π 0 is determined and no evidence of CP violation is found. An independent measurement of D + → K+π +π −π 0 with semileptonic tags is also reported.
