${\Lambda }_c{\Sigma }_c\pi$ coupling and ${\Sigma }_c\to {\Lambda }_c\pi$ decay in lattice QCD

K. U. Can, G. Erkol, M. Oka +1

We evaluate the ${\Lambda }_c{\Sigma }_c\pi$ coupling constant ($G_{{\Lambda }_c{\Sigma }_c\pi }$) and the width of the strong decay ${\Sigma }_c\to {\Lambda }_c\pi$ in 2+1 flavor lattice QCD on four different ensembles with pi…
