Radiative decays of the $\Lambda(1520)$ as a dynamically generated resonance
In the chiral unitary approach with dimensional regularization and new photon-baryon diagrams, the computed Lambda(1520) to gamma Sigma0 width matches BESIII data while the gamma Lambda width underpredicts the CLAS result.
