摘要：
The null results from measurements of the polarization of prompt muons produced by 400-GeV protons indicate an upper limit BμσD0+Bμσ D+<10-31 cm2 may be placed upon the production cross section for D particles, where Bμ is the branching ratio for its three-body decay into a meson, neutrino, and muon. Recent measurements suggest Bμ0.07 which indicates σD<7×10-31 cm2. © 1978 The American Physical Society.
