Absorption Regge Cut in πN Backward Scattering

(Received December 26, 1970)

Abstract:

πN backward scattering data above 5 GeV/c are analyzed in terms of the baryon Regge pole exchange and accompanying Regge cut due to the strong absorption. The fit of the cross sections is reasonable. The role of the cut turns out to be very important: (1) The extrapolated magnitude of the Δδ residue at αΔ=\frac{3}{2} is significantly larger than that without the cut. Δδ residue with or without the wrong signature sense zero at αΔ=½ is equally probable. (2) Prediction of polarization in π+ p→pπ+ is quite differnet from that without the cut. Moreover, large polarization in π- p→pπ- is ecpected.
