Non-factorisable contributions of strong-penguin operators in Λ b → Λℓ + ℓ − decays

Abstract We investigate for the first time a certain class of non-factorisable contributions of the four-quark operators O $$ \mathcal{O} $$ 3−6 in the weak effective Hamiltonian to the Λ b → Λℓ + ℓ − decay amplitude. We focus on the case where a virtual photon is radiated from one of the light cons...
