In this work, we assign the tetraquark state for $Y(4230)$ resonance,and investigate the mass and decay constant of $Y(4230)$ in the framework of SVZ sum rules through a different calculation technique. Then we calculate the strong coupling $g_{Y J/\psi f_0}$ by considering soft-meson approximation techniques, within the framework of light cone sum rules. And we use strong coupling $g_{Y J/\psi f_0}$ to obtain the width of the decay $Y(4230)\to J/\psi f_0(980)$.Our prediction for the mass is in agreement with the experimental measurement,and that for the decay width of $Y(4230)\to J/\psi f_0(980)$ is within the upper limit.

“…Therefore, the upper limits on the products of the two-electron partial width and the branching fractions of Y(4230) and Y(4260) → Ξ − Ξ+ at the 90% C.L. are determined using a Bayesian approach [38,39] to be Γ ee B Y(4230) < 0.33 × 10 −3 eV and Γ ee B Y(4260) < 0.27 × 10 −3 eV taking into account the systematical uncertainty, which may help understand the nature of Y(4260) [67][68][69][70][71][72][73]. In particular, charmless decays of the Y(4260) are predicted by the hybrid model [70].…”

The standard model of particle physics is a well-tested theoretical framework, but there are still some issues that deserve experimental and theoretical investigation. The Ξ resonances with strangeness S=−2, the so-called doubly-strange hyperon, can provide important information to further test the standard model by studying their electromagnetic form factors, such as probing the limitation of the quark models and spotting unrevealed aspects of the QCD description of the structure of hadron resonances. In this work, we review some recent studies of the electromagnetic form factors on doubly-strange hyperons in pair production from positron–electron annihilation experiment.

“…However, as previously mentioned, there are not enough molecular candidates involving Sand P-wave charmed mesons. The most solid candidate is the Y (4230), theorized to be a 1 −− D D1 bound state [3][4][5][6][7][8][9] (though its nature is far from clear and other explanations exist [10][11][12][13][14][15][16][17]). With this we can single out one coupling or combination of couplings that is responsible for its binding, and set the other couplings to zero.…”

“…Both are charmonium-like vector states that were not expected in the quark-model and their nature still remains elusive. The Y (4230) has been proposed to have a sizable D 1 D molecular component [3][4][5][6][7][8][9], which is the premise we will use in this work, though there are other interesting conjectures about its nature [10][11][12][13][14][15][16][17]. The Y (4360) is also suspected to have non-charmonium components [13,15,18].…”
