In this talk I report on the recent developments in the subject of dynamically generated resonances. In particular I discuss the γp → K 0 Σ + and γn → K 0 Σ 0 reactions, with a peculiar behavior around the K * 0 Λ threshold, due to a 1/2 − resonance around 2035 MeV. Similarly, I discuss a BES experiment, J/ψ → ηK * 0K * 0 decay, which provides evidence for a new h 1 resonance around 1830 MeV that was predicted from the vector-vector interaction. A short discussion is then made about recent advances in the charm and beauty sectors.

“…The fact that ordinary decay channels of this state are not allowed, because of its quantum numbers and structure, has probably been a reason why this state is not catalogued in the PDG [26]. Yet, a lucky coincidence, the measurement of the J/ψ → ηK * 0K * 0 decay by the BES Collaboration [27] searching for the Y (2175), now catalogued as φ(2170) in the PDG (which incidentally was not found in Ref. [27], see Ref.…”

Test of h1(1830) made of $$K^* \bar K^$$ with the $$\eta _c \to \varphi K^ \bar K^*$$ decay

We present a new reaction, complementary to the J/ψ → ηK * 0K * 0 from which an h 1 resonance with mass around 1830 MeV was reported from a BESIII experiment. The new reaction is η c → φK * K * , or η c (2S) → φK * K * . Using the information from the analysis of J/ψ → ηK * 0K * 0 , we find that the K * K * invariant mass distribution for those two η c decays exhibits a clear peak around 1830 MeV perfectly distinguishable from what one obtains with pure phase space. We suggest the implementation of these reactions to assert the existence of this elusive resonance which, by its nature as a vector-vector molecule with 0 − (1 +− ) quantum numbers, only couples to the K * K * channel.
