Revisiting radiative decays of $$1^{+-}$$ 1 + - heavy quarkonia in the covariant light-front approach
Abstract We revisit the calculation of the width for the radiative decay of a $$1^{+-}$$ 1 + - heavy $$Q \bar{Q}$$ Q Q ¯ meson via the channel $$1^{+-} \rightarrow 0^{-+} +\gamma $$ 1 + - → 0 - + + γ in the covariant light-front quark model. We carry out the reduction of the light-front amplitude in...
