Study of k+ p ---> k0 delta++(1236), k- p ---> anti-k0 n, and k- p ---> anti-k0 delta0(1236)

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.

Phys.Rev.D 9 (1974) 42-48, 1974.

Inspire Record 93128 DOI 10.17182/hepdata.21955

We have studied the reactions K+p→K0Δ++(1236) at 15.7 GeVc, K−p→K¯0n at 10.7 and 15.7 GeVc, and K−p→K¯0Δ0(1236) at 15.7 GeVc in the BNL Double Vee Magnetic Spectrometer. The π+ and π− from the decays of forward K0's were detected and the above reactions were identified by a missing-mass technique. Total and differential cross sections are presented for the first two reactions and a total cross section for the third.

Systematic Study of K+- Charge Exchange from 3-GeV/c to 6-GeV/c

Diebold, R. ; Ayres, D.S. ; Greene, A.F. ; et al.

Phys.Rev.Lett. 32 (1974) 904, 1974.

Inspire Record 89016 DOI 10.17182/hepdata.21284

Differential cross sections for K−p→K¯0n and K+n→K0p have been measured at 3, 4, and 6 GeV/c using a data sample of 6000 events. Contrary to simple exchange-degenerate models, the ratio of K+ to K− cross sections was found to be approximately 1.35, with little dependence on either s or t. Both reactions show a shallow dip near the forward direction, suggesting the importance of spin-flip amplitudes.
