Proton-Nucleus Interactions at Tevatron Energy

Proton-nucleus interactions at Tevatron highest energy are studied by using the different target nuclei (aluminum, copper, tin and tungsten). Particle production mechanism in pA collision can be studied through target mass dependence on angular distribution of secondary charged particle as well as multiplicity distribution with various target nuclei of aluminum, copper, tin and tungsten. Considering the result of previous 400 GeV/c proton-nucleus experiment by means of nuclear emulsion chamber, we can also investigate energy dependence of various quantities such as momenta in multiplicity distribution, rapidity density and absorption cross sections. We propose to perform same kind of exposure as previous experiment but by 800 GeV proton beam.
