Abstract We study the $$D^+ \rightarrow {\bar{K}}^0 \pi ^+ \eta $$ D + → K ¯ 0 π + η reaction where the $$a_0(980)$$ a 0 ( 980 ) excitation plays a dominant role. We consider mechanisms of external and internal emission at the quark level, hadro

Abstract Starting from the molecular picture for the $$D_{s1}(2460)$$ D s 1 ( 2460 ) and $$D_{s1}(2536)$$ D s 1 ( 2536 ) resonances, which are dynamically generated by the interaction of coupled channels, the most important of which are the $$D^*K$$

Abstract We perform a theoretical study of the $$J/\psi \rightarrow \omega (\phi ) K^* \bar{K} + c.c. \rightarrow \omega (\phi ) K^0 \pi ^+ K^-$$ J / ψ → ω ( ϕ ) K ∗ K ¯ + c . c . → ω ( ϕ ) K 0 π + K - reactions with the assumption that

We face the inverse problem of obtaining the interaction between coupled channels from the correlation functions of these channels. We apply the method to the interaction of the D0K+, D+K0, and Ds+η channels, from where the Ds0⁎(2317) state emerge

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 appe

We reassess the decay of the J/ψ into an ω,ϕ,K⁎0 and one of the f0(1370), f0(1710), f2(1270), f2′(1525), K0⁎(1430) and K2⁎(1430) resonances. We benefit from previous works that considered this reaction as a J/ψ decay into three vector mes

Abstract We study for the first time the $$p\varSigma ^-\rightarrow K^-d$$ p Σ - → K - d and $$K^-d\rightarrow p\varSigma ^-$$ K - d → p Σ - reactions close to threshold and show that they are driven by a triangle mechanism, with the $$\varLamb

We have a look at the Pcs states generated from the interaction of D¯(⁎)Ξc(′⁎) coupled channels. We consider the blocks of pseudoscalar-baryon (12+,32+) and vector-baryon (12+,32+), and find 10 resonant states coupling mostly to D¯Ξc,D¯⁎

Abstract We study the $$D^+ \rightarrow \pi ^+ \eta \eta $$ D + → π + η η and $$D^+ \rightarrow \pi ^+ \pi ^0 \eta $$ D + → π + π 0 η reactions, which are single Cabibbo suppressed and can proceed both through internal and external emission

Abstract We develop a model to study the $$D^0 \rightarrow K^- \pi ^+ \eta $$ D 0 → K - π + η weak decay, starting with the color favored external emission and Cabibbo favored mode at the quark level. A less favored internal emission decay mode i
