Determination of the s-wave pion-nucleon threshold scattering parameters from the results of experiments on pionic hydrogen
G. C. Oades, G. Rasche, W. S. Woolcock +2
We give the conversion equations which lead from experimental values of the transition energy in pionic hydrogen and the total width of the level to values of the…
New light on electromagnetic corrections to the scattering parameters obtained from experiments on pionium
A. Gashi, G. C. Oades, G. Rasche +1
We calculate the electromagnetic corrections needed to obtain isospin invariant hadronic pion-pion s-wave scattering lengths a^0, a^2 from the elements a_cc, a_0c of the s-wave sca…
The influence of the hadronic interaction on the pionium wave functions
A. Gashi, G. Rasche, W. S. Woolcock
The influence of the hadronic ππinteraction on the wave functions of pionium (the Coulomb bound π^+π^- system) at distances less than 10 fm is calculated for s-states with principa…
The effect of vacuum polarisation on muon-proton scattering at small energies and angles
A. Gashi, G. Rasche, W. S. Woolcock
We give a compact expression for the unpolarised differential cross section for muon-proton scattering in the one photon exchange approximation. The effect of adding the vacuum pol…
Electromagnetic corrections for the analysis of low energy pi-p scattering data
A. Gashi, E. Matsinos, G. C. Oades +2
We calculate the electromagnetic corrections to the isospin invariant mixing angle and to the two eigenphases for the s and p-waves for low energy pi-p elastic and charge exchange…
Electromagnetic corrections to the hadronic phase shifts in low energy pi+p elastic scattering
A. Gashi, E. Matsinos, G. C. Oades +2
We calculate the s and p-wave electromagnetic corrections which must be subtracted from the nuclear phase shifts obtained from the analysis of low energy pi+p elastic scattering da…
