Coincidence electroproduction of single neutral pions in the resonance region at q 2 = 0.5 (GeV/ c ) 2

Latham, A. ; Allison, J. ; Booth, I. ; et al.
Nucl.Phys.B 156 (1979) 58-92, 1979.
Inspire Record 1392686 DOI 10.17182/hepdata.836

Data are presented for the reaction ep → ep π 0 at a nominal four-momentum transfer squared of 0.5 (GeV/ c ) 2 . The data were obtained using an extracted electron beam from NINA and two magnetic spectrometers for coincidence detection of the electron and proton. Details are given of the experimental method and the results are given for isobar masses in the range 1.19 – 1.73 GeV/ c 2 .

The (e,e′$p_0$) coincidence cross section for $^{12}$C at transfer energy of 40 MeV

Tadokoro, T. ; Hotta, T. ; Miura, T. ; et al.
Nucl.Phys.A 575 (1994) 333-347, 1994.
Inspire Record 1389768 DOI 10.17182/hepdata.36530

The energy spectra and angular distributions of protons from the 12C(e,e′p) coincidence reaction have been measured at azimuthai angles of φp= −45° and −135° out of the scattering plane, at energy transfer of 40 MeV and momentum transfer of 0.35 fm−1 (69 MeV/c). The longitudinal-transverse interference term, as well as the non-interference term of the (e,e'p0) cross section have been obtained, and the transition amplitudes are deduced in the LS coupling basis. The cross sections are compared with an RPA calculation. The photo-reaction cross section derived from the transverse term is in reasonable agreement with previous experimental results.

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.

Inspire Record 1389651 DOI 10.17182/hepdata.29449

The ration R = σ(e + = p)/σ(e − + p) of the elastic scattering cross section of positrons and electrons on protons was measured at momentum transfers of 11.66 fm −2 and 35.1 fm −2 . The results are consistent with R = 1.

The ratio R = σ (e + + p)/ σ (e − + p) of the elastic scattering cross-section detecting the recoil proton at 0 o in coincidence with the backward electron or positron was found to be R = 1.036 ± 0.018 at q 2 = 8 fm −2 , R = 1.079 ± 0.046 at q 2 = 32 fm −2 .

Pion Resonances Accompanying Strange Particle Production in 7.5-GeV π- - p Interactions

Sov.Phys.JETP 19 (1964) 1326-1332, 1964.
Inspire Record 1387584 DOI 10.17182/hepdata.17001

The simultaneous production of pion resonances and strange particles was investigated. The simultaneous production of p 0 mesons and A-K pairs was observed in events characterized by charged particle multiplicity ns = 4 and having cross sections upo = 20 ± 8 ~b. Cross sections for the production of w and YJ resonances are presented. The 1340-MeV peak in the distribution of four-pion effective masses is discussed.
