Abstract

(1977). doi:10.1016/0370-2693(77)90417-8, We present the first data on the inclusive structure function for π 0 -electroproduction. The data are compared to charged pion electroproduction and charged pion production from electron-positron annihilation taking the quark-parton model as a guide.

Abstract

(1978). doi:10.1016/0550-3213(78)90177-3, The ratio R = σ L σ T of longitudinal and transverse cross sections for the reaction ep → ep η at the resonance S 11 (1535) was measured at momentum transfers q 2 = 0.6 and 1 GeV 2 . The transverse part dominates the longitudinal part of the cross-section. Averaging from W = 1.49 GeV to W = 1.58 GeV we obtain R = 0.22±0.23 at q 2 = 0.6 GeV 2 and R = −0.16 ± 0.16 at q 2 = 1 GeV 2 .

Abstract

(1978). doi:10.1007/BF02896342, We measured 30 000 wide-angle electron-positron pairs from the reaction γ+p→p+e++e− in the invariant-mass region 500≤m≤1060 MeV. The photoproduction amplitudes of the ρ, ω and ϕ mesons were measured to deviate from being pure imaginary by 37.5°−3.1°+2.8°, 29.6°−12.9°+15.5°, 3.4°−4.2°+5.3°,respectively.

Abstract

(1977). doi:10.1016/0370-2693(77)90656-6, The four cross section components σ U , σ L , σ P and σ I were separated in the reaction γ V + p → π + + n at an electron four momentum transfer of Q 2 = 0.70 GeV 2 and an invariant hadronic mass of 2.19 GeV in the range of t between t min and −0.28 GeV 2 . The longitudinal cross section σ L dominates at small |t| and decreases rapidly with increasing |t|. The data are in rough agreement with the prediction of a generalized Born term model. The resulting value for the pion electromagnetic form factor is F π = 0.42 ± 0.015.

(1978). doi:10.1016/0550-3213(78)90045-7, We report on the measurement of the process e + p → e + p + π 0 at energies above the resonance region. The pions are predominantly produced perpendicular to the electron scattering plane. The cross section shows a dip at the minimum momentum transfer. Both features are expected from comparison with photoproduction.
