AbstractAbstract
[en] Gauge-invariant expressions for the amplitudes of strong an electromagnetic decays A1 →πp and A1 → πy are found within the superconducting quark model taking into account π → A1 transitions. The procedure of fixation of ambiguity due to surface terms in these diagrams is discussed in detail
