Electron-positron annihilation into two and three photons around the psi
The authors study the effect of the direct decay of a psi into three photons on electron-positron annihilation into two and three photons. In a charmonium-like bound state model they find a clear effect in e /sup +/e/sup -/ to 3 gamma and a somewhat less pronounced effect in e /sup +/e/sup -/ to 2 g...

| description | The authors study the effect of the direct decay of a psi into three photons on electron-positron annihilation into two and three photons. In a charmonium-like bound state model they find a clear effect in e /sup +/e/sup -/ to 3 gamma and a somewhat less pronounced effect in e /sup +/e/sup -/ to 2 gamma , the actual size depending strongly on the charge of the psi constituents. The effect is reduced when one takes initial state radiative corrections into account. (12 refs). |
