The invariant cross sections for inclusive ..lambda../sup 0/ production by 12-GeV protons on nuclei have been measured for three nuclear targets, beryllium, copper, and tungsten. Data are obtained at three production angles of 3.5/sup 0/, 6.5/sup 0/, and 9.5/sup 0/ in the laboratory, which cover the kinematic range 0.2< or =x/sub F/< or =0.9 and 0.35< or =p/sub T/< or =1.7 GeV/c. The present results are compared with other work at higher energies in terms of the A dependence, Feynman scaling, the p/sub T/ distribution, and triple-Regge behavior. |
