$\Psi(2S)$ decay to $J/\Psi(1S)$ +2$\pi$ or $J/\Psi(1S)$ + $\sigma$ + 2$\pi$

The BES Collaboration has measured $\Psi(2S)$ decay to $J/\Psi \pi^+\pi^-$. Using the mixed hybrid theory for the $\Psi(2S)$ we estimate the decay to $J/\Psi(1S)$ + $\sigma$. Using the known $\sigma \rightarrow 2\pi$ coupling constant, we estimate the $\Psi(2S)$ to $J/\Psi(1S)$ + $2\pi$ decay rate and angular distribution. This is an extension of our previous research on $\Psi(2S)$ Decay to $J/\Psi(1S)$ +$\sigma$ + 2$\pi^o$, without the production of 2$\pi^o$, and with an estimate of the $\sigma \rightarrow \pi^+ + \pi^-$ transition.

Multiquark Cluster Form Factors In the Relativistic Harmonic Oscillator Model

A QCD multiquark cluster system is studied in the relativistic harmonic oscillator potential model (RHOPM), and the electromagnetic form factors of the pion, proton and deuteron in the RHOPM are predicted. The calculated theoretical results are then compared with existing experimental data, finding very good agreement between the theoretical predictions and experimental data for these three target particles. We claim that this model can be applied to study QCD hadronic properties, particularly neutron properties, and to find six-quark cluster and/or nine-quark cluster probabilities in light nuclei such as helium $^{3}He$ and tritium $^{3}H$. This is a problem of particular importance and interest in quark nuclear physics.
