FCNC transitions of $$\Lambda _b$$ Λb to neutron in Bethe–Salpeter equation approach

Abstract In a covariant quark–diquark model, we investigate the rare decay of $$\Lambda _b \rightarrow n l^+ l^-$$ Λb→nl+l- and $$\Lambda _b \rightarrow n \gamma $$ Λb→nγ in the Bethe–Salpeter equation approach. In this model the baryons are treated as bound states of a constituent quark and a diqua...
