    Abstract

    The general formula of the π- p atom strong energy-level shift in the 1s state is derived in the next-to-leading order in the isospin breaking, and in all orders in chiral expansion. Isospin-breaking corrections to the level shift are explicitly evaluated at order p2 in ChPT. The results clearly demonstrate the necessity to critically reaccess the values of the π N scattering lengths, extracted from the energy-level shift measurement by means of the potential model-based theoretical analysis.
