Photoproduction of neutral rho mesons from complex nuclei

Alvensleben, H. ; Becker, U. ; Bertram, W.K. ; et al.

Phys.Rev.Lett. 24 (1970) 786-792, 1970.

Inspire Record 62918 DOI 10.17182/hepdata.21623

We present results of measurements on photoproduction of ρ mesons. Analysis of 106 measured ρ events in a four-dimensional data matrix dσ(A, m, p, t⊥)dΩdm with dimensions 14×20×10×20 yields precise information on nuclear density distributions for ρ production. We obtain for the Woods-Saxon radii R(A)=(1.12±0.02)A13 and, using the vector dominance model, σρN=26.7±2.0 mb and γρ24π=0.57±0.10.

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.

Production of the g(1640) Meson in pi p Interactions at 6 GeV/c

Crennell, D.J. ; Karshon, U. ; Lai, K.W. ; et al.

Phys.Lett.B 28 (1968) 136-139, 1968.

Inspire Record 54727 DOI 10.17182/hepdata.29107

We present the results of a spin determination of the g 1 − (1640) meson from an analysis of its dipion decay mode (π − π 0 ), and find that spin three (or maybe greater) is favored [1,2]. We also report on the observation of an isospin one KK̄ enhancement at 1640 MeV which is consistent with a new decay mode of the g meson. A relative branching ratio of (K K ̄ /ππ) = 8 ± 3 8 % is obtain from our analysis.

Charged-Pion Photoproduction from Deuterium with Polarized Bremsstrahlung

Liu, F.F. ; Drickey, D.J. ; Mozley, R.F. ;

Phys.Rev. 136 (1964) B1183-B1186, 1964.

Inspire Record 1186786 DOI 10.17182/hepdata.26721

Measurements have been made on the ratio of pion-production cross sections at right angles to and along the photon electric-field vector. The positive and negative pions were first momentum-analyzed and counted by means of a counter telescope. Data have been taken at 45, 90, and 135° in the c.m. system, and at proton energies of 225, 330, and 450 MeV. A comparison of the data is made with the dispersion-relation calculation of McKinley.
