ΛcΣcπ coupling and Σc → Λcπ decay in lattice QCD
(Elsevier, 2017-05-10)
We evaluate the Lambda(c)Sigma(c)pi coupling constant (G(Lambda c)Sigma(c)pi) and the width of the strong decay Sigma(c) -> Lambda(c)pi in 2 + 1flavor lattice QCD on four different ensembles with pion masses ranging from ...
Ξcγ→Ξc ′ transition in lattice QCD
(Elsevier, 2017-09-10)
We evaluate the electromagnetic Ξcγ→Ξc ′ transition on 2+1 flavor lattices corresponding to a pion mass of ∼156 MeV. We extract the magnetic Sachs and Pauli form factors which give the Ξc–Ξc ′ transition magnetic moment ...
