Pi- Electroproduction Off Deuterium Above the Resonance Region

Brauel, P. ; Canzler, T. ; Cords, D. ; et al.
Phys.Lett.B 65 (1976) 184-186, 1976.
Inspire Record 114029 DOI 10.17182/hepdata.27606

The reactions e + d → e ' + p S + p + π − and e + d → e ' + n S + n + π + were measured detecting electron and pion in coincidence at an invariant hadronic mass of 2.19 GeV. The measurements were performed at electron four-momentum transfer squared of f 2 = 0.70 and 1.35 GeV 2 in the range of t = ( γ v − π ) 2 between t min and −1.0 GeV 2 . The cross section d 2 σ / dtdφ of the reaction e + n → e' + p + π − was determined.

The reaction pi+ p ---> omega delta++(1236) at 11.7 gev/c

Evans, D. ; Maddock, R.O. ; Pinter, G.F. ; et al.
Nucl.Phys.B 51 (1973) 205-220, 1973.
Inspire Record 84297 DOI 10.17182/hepdata.32709

For the reaction π + p → ωΔ ++ data on the total cross section ( σ = 61 ± 12 μ b), differential cross sections, spin density matrix elements and statistical tensor elements are given. We observe natural and unnatural parity exchange contributions to the total cross section. We note that the value of ϱ 00 is not zero and in the helicity frame exhibits a dip at t ≈ −0.25 (GeV/ c ) 2 . A qualitative theoretical discussion of our results is presented.

Interference between (p,f0 ...) and (rho0,b0,...) exchanges in pion diffraction dissociation at 16 gev/c

The Aachen-Berlin-Bonn-CERN-Heidelberg collaboration Beaupre, J.V. ; Deutschmann, M. ; Graessler, H. ; et al.
Phys.Lett.B 41 (1972) 393-396, 1972.
Inspire Record 75614 DOI 10.17182/hepdata.28235

It is found in the reactions π ± p →( π ± π + π − )p, believed to be dominated by diffraction dissociation, that the d σ d t′ distributions show a “cross-over” effect at t ′ ≈ 0.15, similar to the effect observed in elastic scattering. This gives evidence for the interference of ( ϱ 0 , B 0 ,…)-exchanges with ( P , f 0 , …) -exchanges in pion diffraction dissociation reactions. No such evidence is found for baryon dissociation, π ± p → π ± (p π + π − ), at the same energy.
