Study of high transverse energy processes in 400 GeV proton-nucleus collisions

[摘要] A study has been made of 400 GeV proton-nucleus collisions using a large acceptance calorimeter. The targets used were LH$sb2$, He, Be, C, Al, Cu, Sn and Pb. A geometrically unbiased trigger efficient at selecting hadronic jet events was utilized. The A-dependence of the production of jet-like events is like that seen in high transverse momentum single- and di-hadron production. The dependence upon A of high E$sb{m T}$ production is found to weaken with increasing planarity and when the observed event p$sb{m T}$ balance improves. The flow of energy in the events is found to have a number of features in common with soft high-energy proton-nucleus collisions.
