A sample of 43000 two-prong events obtained at a momomentum of 11.7 GeV/c is used to determine the cross-sections of the fitted channels, and to study the reaction π+p→π+pπ0. We investigate in particular the quasi-two-body channels π0Δ++ and ρ+p.

Reaction pi+ p ---> eta0 delta++ - a test of a2 regge pole exchange

Grether, D.F. ; Gidal, G. ;
Phys.Rev.Lett. 26 (1971) 792-795, 1971.
Inspire Record 69010 DOI 10.17182/hepdata.21507

New results are presented on the reaction π+p→η0Δ++ between 1.2 and 2.67 GeVc. The data above 2 GeVc, when combined with some existing data, give evidence for a dip in the t distribution near t=−1.5 (GeVc).2 This dip, and other features of the data, are adequately described by an A2 Regge-pole model. The effective A2 trajectory is calculated and found to disagree with that obtained from the reaction π−p→η0n.
