Electromagnetic corrections for the analysis of low energy scattering data

Electromagnetic corrections for the analysis of low energy π−p scattering data

We calculate the electromagnetic corrections to the isospin invariant mixing angle and to the two eigenphases for the s-, p1/2and p3/2-partial waves for π −p elastic and charge exchange scattering. These corrections have to be applied to the nuclear quantities in order to obtain the two hadronic phase shifts for each partial wave. The calculation uses relativised Schrödinger equations containin...

Electromagnetic corrections to the hadronic phase shifts in low energy πp elastic scattering

We calculate for the s-, p1/2and p3/2-waves the electromagnetic corrections which must be subtracted from the nuclear phase shifts obtained from the analysis of low energy πp 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 o...

Electromagnetic Corrections to Charged Pion Scattering at Low Energies

The electromagnetic corrections to the low energy scattering amplitude involving charged pions only are investigated at leading and next-to-leading orders in the twoflavour chiral expansion. As an application, the corresponding variation in the strong 2S − 2P level shift is evaluated. The relative variation is of the order of 5%.

F - 13288 Marseille – Cedex 9 Electromagnetic Corrections to Low - Energy π − π Scattering †

Electromagnetic corrections to the low-energy π+π− → π0π0 scattering amplitude at next-to-leading order in the chiral expansion are reviewed. Their effects on the corresponding scattering lengths are estimated and compared to the two-loop strong interaction contributions. Key-Words: Chiral perturbation theory, Pion, Electromagnetic corrections. Contribution to the Eighth International Symposium...
