Compton scattering from the proton at fourth order NLO in the chiral expansion. [Erratum to document cited in CA135:98269].

Two errors were made in the evaluation of the Compton scattering cross sections. One was in the fourth-order contributions given in Appendix A, namely the contribution from diagram (1h). This error does not affect the polarizabilities and has very little effect on the cross sections. The other error was in the coding of the third-order contribution for some angles, and this had more effect. The replacements for Figures 2, 3, 5, 6, and 7 contain addnl. data points, some new (Olmos de Leon et al., 2001) and some old (Baranov et al., 2001), and revised Illinois data (F. J. Federspiel et al., 1991). The conclusions of the original paper are not substantially affected, but it is clear that the failure of the chiral expansion at high energies starts at more forward angles than originally thought.
