Total Cross-Section of the Reaction K- p --> anti-K0 n from 515-MeV/c to 1065-MeV/c

Alston-Garnjost, M. ; Kenney, R.W. ; Pollard, D.L. ; et al.

Phys.Rev.D 17 (1978) 2216, 1978.

Inspire Record 121139 DOI 10.17182/hepdata.24429

We report the results of a precise measurement of the K−p→K¯0n cross section between 515 and 1065 MeV/c in steps of 10 MeV/c. The statistical errors are less than 1%, a major improvement in accuracy over previous work. We discuss in detail the experimental apparatus and the corrections made to the data. No evidence is found for the new I=1 K¯N resonances at 546 and 602 MeV/c K− momenta reported recently by Carroll et al.

Proton-antiproton annihilation into pi+ pi- and k+ k- from 700 to 1100 mev/c

Mandelkern, M.A. ; Burns, R.R. ; Condon, P.E. ; et al.

Phys.Rev.D 4 (1971) 2658-2666, 1971.

Inspire Record 74756 DOI 10.17182/hepdata.23118

Total and differential cross sections are presented for proton-antiproton annihilation into π+π− and K+K− at six laboratory momenta between 686 and 1098 MeV/c. The two-pion final state displays moderate energy dependence in its differential cross section, but shows no evidence of any direct-channel resonances. In contrast, the two-kaon final state exhibits some behavior in the total and differential cross section suggestive of a possible direct-channel effect between 800 and 1000 MeV/c.

Electron-Proton Scattering at High-Momentum Transfer

Berkelman, K. ; Feldman, M. ; Littauer, R.M. ; et al.

Phys.Rev. 130 (1963) 2061-2068, 1963.

Inspire Record 46839 DOI 10.17182/hepdata.26788

The elastic electron-proton scattering cross section has been measured at laboratory angles between 90° and 144° and for values of the four-momentum transfer squared between 25 and 45 F−2 (incident electron laboratory energies from 830 to 1360 MeV). Both the scattered electrons and the recoil protons were momentum analyzed and counted in coincidence, making possible background-free measurements down to cross sections of the order of 10−35 cm2/sr. The data are consistent with the Rosenbluth formula, and the resulting form factors tie on well with previous measurements at lower momentum transfer, continuing the established trend.
