Cross Section Measurement in MIPP

The Main Injector Particle Production (MIPP) Experiment (FNAL-E907) is a fixed target experiment at Fermilab. The purpose of the experiment is to measure hadronic particle production using primary 120 GeV/c protons and secondary $\pi \pm $, K$\pm $, p$\pm $ beams and target nuclei spanning the periodic table from hydrogen to uranium. Particle identification uses a Time Projection Chamber (TPC), Time of Flight (TOF), Threshold Cherenkov (Ckov), and Ring Imaging Cherenkov (RICH) detectors in a wide range of particle momenta from 5 GeV/c up to 120 GeV/c. We present the status of data analysis to determine cross sections of 58 GeV/c $\pi $/K/p beams on a thin carbon target.
