Electromagnetic corrections to the hadronic phase shifts in low energy π+p elastic scattering Original Research Article

We calculate for the s-, View the MathML source- and View the MathML source-waves the electromagnetic corrections which must be subtracted from the nuclear phase shifts obtained from the analysis of low-energy π+p elastic scattering data, in order to obtain hadronic phase shifts. The calculation uses relativised Schrödinger equations containing the sum of an electromagnetic potential and an effective hadronic potential. We compare our results with those of previous calculations and estimate the uncertainties in the corrections.
