Inclusive pi- and gamma Production in 24-GeV/c p p Collisions

We report the 24-GeV/c inclusive ..pi../sup -/ yield near theta/sub c.//sub m./=90degree for 0.5< or =P/sub T/approximately-less-than2.2 GeV/c. No high-P/sub T/ excess is seen at this energy. In addition we have obtained the inclusive ..gamma..-ray yield from a measurement of low-mass e/sup +/e/sup -/ pairs. This yield is compared with that expected from ..pi../sup 0/-, eta-, and ..omega..-meson decay, to provide limits on possible photon production. (AIP)
