Suppression of decay widths in singly heavy baryons induced by the $$U_A(1)$$ anomaly

Kawakami, Yohei*; Harada, Masayasu*; Oka, Makoto  ; Suzuki, Kei 

We study strong and radiative decays of excited singly heavy baryons using an effective chiral Lagrangian based on the diquark picture. The effective Lagrangian contains a $$U_A(1)$$ anomaly term, which is found to suppress the decay width of $$Lambda_Q(1/2^-) to Lambda_Q(1/2^+)eta$$.
