Abstract

© 2021, The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature.The strong coupling constants of spin-3/2 to spin-1/2 doubly heavy baryon transitions with light vector mesons are estimated within the light-cone QCD sum rules method. Moreover, using the vector-meson dominance ansätz, the widths of radiative decays BQQ∗→BQQγ are calculated. The results for the said decay widths are compared to the predictions of other approaches.
