N2 - The dynamics of the JPC=0-+, 0++, and 2++ resonance contributions to the decay J/ψ→γX(JPC)→γφφ is analysed using the data obtained by BESIII collaboration. The effective coupling constants parameterising invariant amplitudes of the transitions J/ψ→γX(JPC) and X(JPC)→φφ and masses of X(JPC) resonances are found from the fits. They are used for evaluation of the branching fractions BX(JPC)→φφ, relative branching fractions BJ/ψ→γX(JPC)→γφφ, and for obtaining the photon angular distributions.
