Measurements of the absolute branching fractions of D0(+) → K K ππ decays

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− π0 π0, D0 → K0SK0Sπ+ π−, D0 → K0S K− π+ π0, D0 → K0S K+ π−...

Description
Summary: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− π0 π0, D0 → K0SK0Sπ+ π−, D0 → K0S K− π+ π0, D0 → K0S K+ π− π0, D+ → K+ K− π+ π0, D+ → K0S K+ π0 π0, D+ → K0S K− π+ π+, D+ → K0S K+ π+ π−, and D+ → K0S K0Sπ+ π0. The decays D0 → K+ K− π0 π0, D0 → K0S K− π+ π0 , D0 → K0S K+ π− π0, D+ → K0S K0S π+ π0, and D+ → K0S K+ π0 π0 are observed for the first time. The branching fractions of the decays D0 → K0S K0S π+ π−, D+ → K+ K− π+ π0, D+ → K0S K− π+ π+, and D+ → K0S K+ π+ π− are measured with improved precision compared to the world-average values.
