Pi-minus p elastic scattering at 2.51, 2.76, and 3.01 gev/c near t approximately equals -3 (gev/c)-squared

Differential cross sections for the elastic scattering of negative pions from hydrogen have been measured over a limited range of squared four-momentum transfer (t) in the vicinity of t≃−3 (GeV/c)2 for incident pion momenta of 2.51, 2.76, and 3.01 GeV/c. These measurements confirm the existence of a minimum in the differential cross section in this region of incident momentum and scattering angle. The minimum occurs at a smaller value of t [t≃−2.6 (GeV/c)2] than has been observed at higher momenta.

Elastic scattering of negative pions from deuterons at 2.01, 3.77, and 5.53 gev/c

Fellinger, M. ; Gutman, E. ; Lamb, R.C. ; et al.
Phys.Rev.Lett. 22 (1969) 1265-1269, 1969.
Inspire Record 56484 DOI 10.17182/hepdata.21699

The differential cross sections for the elastic scattering of negative pions by deuterons have been measured for 2.01-, 3.77-, and 5.53-GeV/c incident pion momenta, over an interval of the squared four-momentum transfer from -0.25 (GeV/c)2 to ∼-1.0 (GeV/c)2. The results are consistent with calculations based on a Glauber model of the scattering process.

Polarization in pp Elastic Scattering at Large Momentum Transfers

Booth, N.E. ; Conforto, G. ; Esterling, R.J. ; et al.
Phys.Rev.Lett. 21 (1968) 651-652, 1968.
Inspire Record 944913 DOI 10.17182/hepdata.21669

Measurements of the polarization in pp elastic scattering have been made at 5.15 GeV/c over the range −t=0.2 to 1.8 (GeV/c)2. The data are compared with a Regge-pole model, and with the diffraction model of Durand and Lipes in which the absorptive part of the pp interaction is derived from the electromagnetic form factor of the proton. The latter model reproduces the t dependence of the experimental data in a qualitative way.

Pi-+ photoproduction in forward direction

Ito, A. ; Loe, R. ; Loh, E.C. ; et al.
Phys.Rev.Lett. 24 (1970) 687-690, 1970.
Inspire Record 62934 DOI 10.17182/hepdata.21670

The ratio of π− to π+ off deuterium was measured as a function of incident photon energy from 600 to 1700 MeV in the forward direction. The ratio shows a broad dip around a center-of-mass energy of 1700 MeV, resulting presumably from the collective effect of several isospin-½ resonances in this energy region. Such a change in the ratio is reflected in the rapid variation of the isoscalar photoproduction amplitude since we found the isovector photoproduction amplitude to be a relatively smooth function decreasing slowly with increasing incident photon energy.
