Abstract
The reaction pi(-)p --> KSKL pi(-)p is investigated by means of the B- meter ITEP spectrometer irradiated by 40-GeV/c pions from the Serpukho v accelerator. The integrated flux incident on the target is 8 x 10(10 ) pions. A partial-wave analysis of the KSKL pi(-) system is performed for statistics involving more than 8000 events. The number of require d amplitudes is substantially reduced by detecting both K-S and K-L me sons. As the 1(+) wave is found to be dominant and amenable to the par ameter-free Tornqvist description, the conclusion is drawn that the K (K) over bar system is dominated by the a(1) meson at these energies.
