Eta photoproduction on the proton for photon energies from 0.75-GeV to 1.95-GeV

Differential cross sections for γp→ηp have been measured with tagged real photons for incident photon energies from 0.75 to 1.95 GeV. Mesons were identified by missing mass reconstruction using kinematical information for protons scattered in the production process. The data provide the first extensive angular distribution measurements for the process above W=1.75  GeV. Comparison with preliminary results from a constituent quark model support the suggestion that a third S11 resonance with mass ∼1.8  GeV couples to the ηN channel.

Pion - deuteron elastic scattering at large angles from 0.90-GeV/c to 2.025-GeV/c

The differential cross section for the backward (120° ⩽ θ c.m.s. ⩽ 180°) pion-deuteron elastic scattering was measured at eight incident pion momenta from 0.90 to 2.025 GeV/ c . A distinctive change in the shape of the angular distribution is observed. At 0.9 GeV/ c the differential cross section decreases smoothly to 180° in accordance with predictions of multiple-scattering theory. At 1.31 GeV/ c , i.e. in the region of the hypothetical 1 I 6 dibaryon with a mass of 2.9 GeV, the differential cross section is practically independent of angle. At higher energies a sharp backward peak is clearly seen. Connections of our results with dibaryons and Regge asymptotic behaviour are discussed.

Measurements of the differential cross section for π − d elastic scattering in the backward angular region (−1 ⩽ cos θ cms ⩽ −0.98) are presented. These measurements were made at nine incident pion momenta P π ranging from 1.75 to 3.09 GeV/ c and at the largest values of q 2 [up to 7 (GeV/ c ) 2 ] ever reached experimentally; here q 2 is the momentum transfer squared. The differential cross section was found to decrease rapidly with increasing momentum d σ d Ω cms (180°) ∼ P −15.7 π , d σ d t ∼ (q 2 ) −12.8 . The data are compared with predictions of Regge and quark bag models.
