Scalar-Transverse Separation of Electroproduced K+ Lambda and K+ Sigma0 Final States

Bebek, C.J. ; Browman, A. ; Brown, C.N. ; et al.

Inspire Record 4932 DOI 10.17182/hepdata.24615

We present evidence for a large scalar contribution to the cross section for the reaction ep→eK+Λ. No evidence for a scalar contribution is found for the reaction ep→eK+Σ0. This is reminiscent of the results for the π+n and π+Δ0 final states.

Electroproduction of K+ Mesons Along the Virtual Photon Direction

Bebek, C.J. ; Brown, C.N. ; Bucksbaum, P. ; et al.
Phys.Rev.D 15 (1977) 594, 1977.
Inspire Record 110317 DOI 10.17182/hepdata.24604

We report measurements of kaon electroproduction from hydrogen and deuterium targets carried out at the Wilson Synchrotron Laboratory at Cornell University. The reactions γVp→K+X0, K+Γ, and K+Σ0 were studied in the kinematic region 2.15≤W≤3.1 GeV and 1.2<Q2<4.0 GeV2 as a function of Q2, W, and ω. The K+Σ0 cross sections fall much more rapidly with increasing Q2 than the K+Λ cross sections so that K+Σ0KΛ→0 as Q2 increases.
