DCS for π − p elastic scattering from 1.2 to 3.0 GeV/ c and phase shift analysis

Aplin, P.S. ; Cowan, I.M. ; Gibson, W.M. ; et al.
Nucl.Phys.B 32 (1971) 253-284, 1971.
Inspire Record 1104030 DOI 10.17182/hepdata.69638

Differential cross sections have been measured for π − p elastic scattering at laboratory momenta in the range 1.2 to 3.0 GeV/ c for the c.m. range 0.97 > cos θ ∗ > −0.98 . The corresponding mass range is 1.78 to 2.56 GeV/ c 2 . The data was obtained from a counter experiment in which the scattered pions and protons were detected in coincidence by arrays of scintillation counters.

The transverse and longitudinal cross sections for electroproduction of pions near the Δ(1236)-isobar

Bartel, W. ; Dudelzak, B. ; Krehbiel, H. ; et al.
Phys.Lett.B 27 (1968) 660-662, 1968.
Inspire Record 1389642 DOI 10.17182/hepdata.29204

The reaction e + p → e ′+ N ∗ was studied for four momentum transfers up to 2.34 (GeV/ c ) 2 in the region of the 1236 MeV isobar. An analysis of the data in terms of the cross sections σ T and σ L for the absorption of transverse and longitudinal photons is given for invariant masses of the final pion nucleon system W =1.220 GeV and W =1.350 GeV.

Search for solutions of the phase-shift analysis of pp interactions at 970 MeV

Vovchenko, V.G. ; Grebenyuk, O.G. ; Fedorov, O.Ya. ;
Yad.Fiz. 44 (1986) 456-459, 1986.
Inspire Record 239695 DOI 10.17182/hepdata.38007

A random search for solutions of the phase-shift analysis of pp scattering at 970 MeV is carried out. Solutions were selected according to the correct position of the zero of trajectory I of the Barrelet amplitude f1 in addition to the statistical criteria. Two pairs of solutions with similar phase shifts are found as a result. Two of these solutions have been found before

Study of $p p$ Interactions in the Momentum Range 0.9-{GeV}/$c$ to 2.0-{GeV}/$c$

Shimizu, F. ; Koiso, H. ; Kubota, Y. ; et al.
Nucl.Phys.A 389 (1982) 445-456, 1982.
Inspire Record 12089 DOI 10.17182/hepdata.37051

pp interactions at 11 momenta in the range 0.9 to 2.0 GeV/ c have been studied. The elastic angular distributions, covering the c.m. angular range 22°–90°, agree in general with Hoshizaki's phase-shift analysis which shows the looping 1 D in and 3 F 3 amplitudes in the Argand diagram. About 80% of pn π + events come from the n Δ ++ state at all momenta above 1.2 GeV/ c . The behavior of the density matrix elements of the Δ ++ show no momentum or angular dependence. A large fraction of pp π 0 events also come from the p Δ + state at all momenta above 1.2 GeV/ c . The behavior of the Δ + density matrix elements is similar to that for the case of Δ ++ .

A STUDY OF THE REACTION anti-p n ---> pi- pi- pi+ AT CENTER-OF-MASS ENERGIES BETWEEN 1.9-GeV AND 2.3-GeV

Darling, T. ; Opat, G.I. ; Tovey, S.N. ; et al.
Nuovo Cim.A 79 (1984) 181, 1984.
Inspire Record 14076 DOI 10.17182/hepdata.37516

We have studied the reactions\(\bar pn \to \pi ^ -\pi ^ -\pi ^ +(\pi ^0 )\) at incident momenta between 0.42 and 1.65 GeV/c using two exposures in deuterium-filled bubble chambers. The ratio of the rates for 3π to 4π final states shows a sharp increase at a momentum of about 0.8 GeV/c. A full partial-wave analysis of the 3π final state has been made and complex structure is observed at approximately the same momentum, associated in particular with theJP=3+ final state.
