Abstract
We have studied inclusive , , and production and strange-resonance production in the reactions at 405 GeV/c. The observed cross sections are 7.43 ± 0.45 mb for , 4.01 ± 0.35 mb for , and 0.63 ± 0.12 mb for . From the analyses of the effective-mass distributions for the (), (), and () systems, the resonance production cross sections are determined as 4.1 ± 1.0 mb for , 3.6 ± 1.0 mb for , 3.4 ± 1.7 mb for , 0.67 ± 0.12 mb for , 0.45 ± 0.09 mb for , and 0.25 ± 0.08 mb for . The inclusive total and differential cross sections are discussed in comparison with data at lower energies. The direct production cross sections for pseudoscalar, vector, and tensor mesons are estimated to be 2.3 ± 1.2, 3.4 ± 1.0, and 1.7 ± 0.8 mb, respectively. Direct pseudoscalar--meson production accounts for less than one-third of the total inclusive kaon production. Evidence of vector-meson dominance in inclusive meson production at high energy is indicated.
