Revisiting radiative transitions of charmonium states in covariant confined quark model
Aidos Issadykov, Mikhail A. Ivanov, Dang-Khoa N. Nguyen +3
We calculate the amplitudes and branching fractions of , , , and radiative decays in the framework of the covariant confined quark model. First, we exp…
