On the four-quark operator matrix elements for the lifetime of $$\Lambda _{b}$$ Λ b
Abstract Heavy quark expansion can nicely explain the lifetime of $$\Lambda _{b}$$ Λ b . However, there still exist sizable uncertainties from the four-quark operator matrix elements of $$\Lambda _{b}$$ Λ b in $$1/m_{b}^{3}$$ 1 / m b 3 corrections, which describe the spectator effects. In this work,...
