The electromagnetic polarizabilities of the proton and the scalar- isoscalar gamma gamma to pi pi amplitude
In a dispersive approach to the calculation of the electromagnetic polarizabilities of the proton, the sensitivity to the annihilation channel input is analyzed. It is shown that the isoscalar s-wave absorptive part gives the overwhelming contribution. The connection with the poorly known gamma gamm...

| Sumario: | In a dispersive approach to the calculation of the electromagnetic polarizabilities of the proton, the sensitivity to the annihilation channel input is analyzed. It is shown that the isoscalar s-wave absorptive part gives the overwhelming contribution. The connection with the poorly known gamma gamma to pi pi amplitude is established and some numerical estimates are presented. (21 refs). |
