In order to obtain a better understanding of the nature of the (1800), it might be important to search for a corresponding kaon state. Since we intend to also use a kaon beam, the same excitation mechanism for a high mass K-state could be used as for the production of the pion state in a pion beam.
We can tag the incoming kaon with the CEDARs and the final states via the spectrometer Cherenkov counters. Thus, technically, the discovery potential is present. However the much lower kaon fluxes in the beam will reduce the statistics.
After 3 months of running with a 300 GeV/c /K beam we will collect an event sample of few (3-5) times smaller statistics as compared to the currently available statistics in the 3 system and still an order of magnitude more than in the system. These studies can be done also at 160 GeV/c, where the K/ ratio is 0.1 and 0.075 for positive and negative beams respectively and K intensities of up to 1 10 /spill could be obtained . In this case about 3 times larger statistics will be collected.
