Abstract

The results given for the isoscalar combinations of nucleon electromagnetic polarizabilities in [Phys. Lett. B 567 (2003) 200] are incorrect. After correcting errors in our O(Q4) chiral perturbation theory calculation of elastic γd scattering we obtain a fit to recent experimental data with χ2/d.o.f.=26.6/20. For the isoscalar electric polarizability this fit yields αN=(13.0±1.9(stat))-1.5 +3.9(theory), while βN is consistent with zero within sizable error bars. These mistakes in our γd calculation do not affect the results quoted in [Phys. Lett. B 567 (2003) 200] for the proton polarizabilities.
