Measurements of the absolute branching fractions of D0(+) -> K(K)over-bar pi pi decays

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 D-0 -> K+K- pi(0 pi 0), D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS-)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-) D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-), and Dthorn. D-0 -> (KSKS0)-K-0 pi(+)pi(-). The decays D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-), and D-0 -> (KSKS0)-K-0 pi(+)pi(-) are observed for the first time. The branching fractions of the decays D-0 -> (KSKS0)-K-0 pi(+)pi(-), D-0 -> (KSKS0)-K-0 pi(+)pi(-), Dthorn. D-0 -> (KSKS0)-K-0 pi(+)pi(-). D-0 -> (KSKS0)-K-0 pi(+)pi(-) are measured with improved precision compared to the world-average values.
