We e v aluate the amplitude for ! 0 0 to two loops in chiral perturbation theory. The three new counterterms which e n ter at this order in the lowenergy expansion are estimated with resonance saturation. We nd that the cross section agrees rather well with the available data and with dispersion theoretic calculations even substantially above threshold. Numerical results for the Compton cross section and for the neutral pion polarizabilities are also given to two-loop accuracy.]

“…The possibility to measure the pion polarizability via the Primakoff reaction was proposed in the early 1980s in [44]. The measurement of the pion-photon Compton scattering amplitude by using the Primakoff effect was performed in an experiment at Serpukhov [45] , but the small data sample led to only an imprecise value for the polarizability of α π = (6.8 ± 1.4 stat ± 1.2 syst ) × 10 −4 fm 3 . Low statistics made it difficult to evaluate the systematic uncertainty.…”

Abstract. The values of charged pion polarizabilities obtained in the framework of chiral perturbation theory at the level of two-loop accuracy are compared with the experimental result recently reported by COMPASS Collaboration. It is found that the calculated value for the dipole polarizabilities (α − β) π ± = (5.7 ± 1.0) × 10 −4 fm 3 fits quite well the experimental result (α − β) π ± = (4.0 ± 1.2 stat ± 1.4 syst ) × 10 −4 fm 3 .
