Abstract

Based on 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 by the BESIII detector, we report the measurements of the absolute branching fractions of D0→K+K-π0π0, D0→KS0KS0π+π-, D0→KS0K-π+π0, D0→KS0K+π-π0, D+→K+K-π+π0, D+→KS0K+π0π0, D+→KS0K-π+π+, D+→KS0K+π+π-, and D+→KS0KS0π+π0. The decays D0→K+K-π0π0, D0→KS0K-π+π0, D0→KS0K+π-π0, D+→KS0KS0π+π0, and D+→KS0K+π0π0 are observed for the first time. The branching fractions of the decays D0→KS0KS0π+π-, D+→K+K-π+π0, D+→KS0K-π+π+, and D+→KS0K+π+π- are measured with improved precision compared to the world-average values.
