Direct photon production at high p-transverse in pi- Be and p Be collisions at 500-GeV/c

We report new measurements of inclusive direct photon production at high transverse momenta (pT) for π - and p interactions on Be at 500 Gev/r. The yields as a function of pT and rapidity (y) are in good agreement with expectations from next-to-leading-log QCD calculations employing recently extracted quark and gluon structure functions

Performance characteristics and radiation damage results from the Fermilab E706 silicon microstrip detector system

Abstract A charged particle spectrometer containing a 7120-channel silicon microstrip detector system, one component of Fermilab experiment E706 to study direct photon production in hadron-hadron collisions, was utilized in a run in which 6 million events were recorded. We describe the silicon system, provide early results of track and vertex reconstruction, and present data on the radiation damage to the silicon wafers resulting from the narrow high intensity beam.

Production of. pi. sup 0 mesons at high p sub T in. pi. sup minus Be and p Be collisions at 500 GeV/ c

We present new measurements of {pi}{sup 0} production at high transverse momenta ({ital p}{sub {ital T}}) for {pi}{sup {minus}} and {ital p} interactions on Be and Cu targets at 500 GeV/{ital c}. The observed dependence of the yields as a function of {ital p}{sub {ital T}} and rapidity ({ital y}) is compared with expectations from leading-log QCD over a kinematic range in which the inclusive cross sections fall by more than 4 orders of magnitude.
