Energy and Momentum Distributions of Muoproduced Hadrons

We present inclusive distributions for final-state hadrons produced in inelastic muon-proton scattering. Over the total energy range 2<W<4.7 GeV and the momentum-transfer range 0.3<Q2<4.5 GeV2, the fractional momentum and energy distributions approximately scale. Distributions in transverse momentum display an interesting two-component behavior. They show no dependence on the virtual-photon "mass squared" Q2, and have average values typical of other hadron-initiated reactions. A comparison of our distributions with those seen in e+e− annihilation and neutrino-nucleon scattering shows agreement, in support of quark-parton fragmentation ideas. We further break these distributions down by event topology.

Experimental verification of the Kramers-Kronig relation at high energy

Alvensleben, H. ; Becker, U. ; Biggs, P.J. ; et al.

The real part of the forward amplitude for Compton scattering on protons was measured through the interference between the Compton and Bethe-Heithler amplitudes by detecting the zero-degree electron pairs asymmetrically. The measurement was made at an average photon energy of 〈k〉=2.2 GeV, and an average momentum transfer to the recoil proton 〈t〉=−0.027 (GeV/c)2. The result confirms the prediction of the Kramers-Kronig relation.

Study of k- pi- scattering using the reaction k- d ---> k- pi- p p(s)

Cho, Y. ; Derrick, M. ; Johnson, D. ; et al.
Phys.Lett.B 32 (1970) 409-412, 1970.
Inspire Record 63111 DOI 10.17182/hepdata.28719

Approximately 700 events of the reaction K − d → K − π − pp s produced by 5.5 GeV/ c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

Proton form factors from elastic electron-proton scattering

Janssens, T. ; Hofstadter, R. ; Hughes, E.B. ; et al.
Phys.Rev. 142 (1966) 922-931, 1966.
Inspire Record 49127 DOI 10.17182/hepdata.26698

Absolute measurements of the elastic electron-proton cross section have been made with a precision of about 4% for values of the square of the four-momentum transfer, q2, in the range 6.0 to 30.0 F−2 and for electron scattering angles in the range 45° to 145°. To within the experimental errors, it is found that the charge and magnetic form factors of the proton have a common dependence on q2 when normalized to unity at q2=0, and that an accurate representation of the behavior of the form factor and that of the cross sections themselves can be given in terms of a three-pole approximation to the dispersion theory of nucleon form factors.
