An Investigation of the Reaction K¯p → K¯π⁺ at P_(lab) = 2 Gev/c


Chu, David (1972) An Investigation of the Reaction K¯p → K¯π⁺ at P_(lab) = 2 Gev/c. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/ZD9F-W947.


The reaction K-p→K-π+n has been studied for incident kaon momenta of 2.0 GeV/c. A sample of 19,881 events was obtained by a measurement of film taken as part of the K-63 experiment in the Berkeley 72 inch bubble chamber.

Based upon our analysis, we have reached four conclusions. (1) The magnitude of the extrapolated Kπ cross section differs by a factor of 2 from the P-wave unitarity prediction and the K+n results; this is probably due to absorptive effects. (2) Fits to the moments yield precise values for the Kπ S-wave which agree with other recent statistically accurate experiments. (3) An anomalous peak is present in our backward K-p→(π+n) K- u-distribution. (4) We find a non-linear enhancement due to interference similiar to the one found by Bland et al. (Bland 1966).
