Traces of the new $$a_0(1780)$$ a 0 ( 1780 ) resonance in the $$J/\psi \rightarrow \phi K^+K^-(K^0\bar{K}^0)$$ J / ψ → ϕ K + K - ( K 0 K ¯ 0 ) reaction

Abstract We study the $$J/\psi \rightarrow \phi K \bar{K}$$ J / ψ → ϕ K K ¯ decay, looking for differences in the production rates of $$K^+ K^-$$ K + K - or $$K^0 \bar{K}^0$$ K 0 K ¯ 0 in the region of 1700–1800 MeV, where two resonances appear dynamically generated from the vector-vector interactio...
