Pi Zero and Direct Photon Production at High Transverse Moment
- McGill Univ., Montreal, QC (Canada)
The inclusive pizero and direct photon productions by 300 GeV/c $$\pi^-$$ and $$\pi^+$$ beams on a lithium target, were measured using the E705 spectrometer at Fermilab. The cross sections were determined by analyzing a fraction (20%) of the data recorded by the experiment during the 1987-1988 running period. The photons were measured by a high resolution electromagnetic calorimeter which consisted of scintillation and lead glass blocks. A fast trigger was designed and implemented to select events with high transverse energy depositions in the calorimeter. The invariant cross sections are presented as a function of the transverse momentum and the Feynman-x in the range between 4 to 7 GeV/c and -0.25 to 0.35 respectively. The results are compared to the measurements made by other experiments and to theoretical predictions within the framework of Quantum ChromoDynamics.
