Measurements of absolute branching fractions of D0→K0Lϕ, K0Lη, K0Lω, and K0Lη′

• We report the first measurements of the absolute branching fractions of D0→K0Lϕ, D0→K0Lη, D0→K0Lω, and D0→K0Lη′, by analyzing 2.93  fb−1 of e+e− collision data taken at a center-of-mass energy of 3.773 GeV with the BESIII detector. Taking the world averages of the branching fractions of D0→K0Sϕ, D0→K0Sη, D0→K0Sω, and D0→K0Sη′, the K0S−K0L asymmetries R(D0,X) in these decay modes are obtained. The CP asymmetries in these decays are also determined. No significant CP violation is observed.
