Summary
[edit]DescriptionPhysRevC.100.024001.pdf |
English: In this paper, we implement the use of a πNΔ(1232) vertex interaction containing both first- and second-order derivative terms, as required by renormalization and power-counting considerations. As was previously shown, both interactions present quantization shortcomings but can be used in a pertubative calculation. Our results indicate that the usual π derivative plus the spin-3/2 gauge invariant (derivative also in the Δ field) should be included in amplitude calculations, as also all higher derivative interactions respecting chiral invariance. We show that both interactions make essentially the same resonant contribution to the elastic π+p cross section, so changing the ratio between both coupling constants amounts to a correction of the background. The elastic π+p cross section up to 300 MeV changes only mildly when that ratio is changed, but the total π−p scattering, which has poor fit within both interactions separately, can be much improved in the same energy range by tuning the ratio between both coupling constants. |
