ΛcΣcπ coupling and Σc→Λcπ decay in lattice QCD
We evaluate the ΛcΣcπ coupling constant (GΛcΣcπ) and the width of the strong decay Σc→Λcπ in 2+1 flavor lattice QCD on four different ensembles with pion masses ranging from 700 MeV to 300 MeV. We find GΛcΣcπ=18.332(1.476)stat.(2.171)syst. and the decay width Γ(Σc→Λcπ)=1.65(28)stat.(30)syst. MeV on...
