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...
