“…Background was subtracted for each bin in the manner described in an earlier publication. 2 The resulting graph, Fig. 2, shows no sign of a peak at the 7-ray mass squared, and fits the experimental resolution function with the center at the 7r° mass squared.…”

Total and differential cross sections of the reaction K~p -> Arj have been determined for incident K~ lab momenta between 1.2 and 1.7 BeV/c. No striking resonance formation in the direct channel is seen; in particular, the Fo*(2100) decays not more than 3% via the Arj channel. A prominent forward peak in the differential cross sections indicates some crossed-channel meson-exchange activity. The branching ratio r 0? -> neutrals)/r(TJ -»?r WO is 3.6d=0.6.

“…--> A7r + 7r T described in Ref. 2 was subtracted in each angular bin; however, we assumed that the background for the rj's is linear from 505 to 595 MeV, rather than drawing a background curve by eye as was done in the co case. Our results, combined with those of Sec.…”

“…Previous work based in part on a fraction of the data presented here (approximately one-third of the total data at 1.51 BeV/c) indicated a very low__branching ratio of the 1660-MeV isobar into the KN system (Tj^/Ttotai = #~0.04). 18 The experiment of Bastien and Berge was shown to be inconsistent with a value of x smaller than 0.16. 19 In appraising the significance of this discrepancy, we must remember the difficulties associated with studying a resonance with a relatively low production cross section in the presence of a much stronger effect (K* in this case).…”

“…Firstly, study of high energy ir~p interactions at Berkeley has given a value of approximately 0.2 for x. 20 Then, if we use the F*(1660) branching ratio given by Alvarez et al, 18 x turns out to be less than or equal to 0.04. Thus all indications are that the Y*KN decay rate is quite low, although the exact value is still undetermined.…”

This report summarizes the study of the reaction K~p -> K°TT~P over the range of energies from 1.0 to 1.7 BeV/c. The reaction is shown to be dominated by the K*~p final state from threshold (1.08 BeV/c) to the highest energy available in this experiment. The best values for K*~~ parameters are shown to be 891 and 46 MeV for the central value and full width of the resonance, respectively. It is shown that the one-pionexchange contribution dominates the low-momentum-transfer events at the higher energies. On the assumption that T = 3/2 KTT interaction is negligible, which is strongly indicated by the data of Galtieri et aL, the T = 1/2 KTT S-wave phase shift is shown to be small and positive and roughly linear with the center-of-mass momentum in the Kir system. Influence of other unstable meson and baryon states on this reaction is discussed.
