[en] Preliminary results on large transverse momentum direct photon and π⁰ production in π^-p, π⁺p and pp collisions at 300 GeV/c are presented. A clear signal for direct photon production is observed in all reactions for transverse momenta P_T > 4 GeV/c. The cross sections are measured up to P_T = 7 GeV/c (x_T = 0.6) in π^-p and up to P_T = 6 GeV/c (x_T=0.5) in π⁺p and pp collisions. At large P_T, the direct photon production cross section is increasing in π^-p collisions relative to π⁺p collisions as expected from valence quark-antiquark annihilations. The π⁰ production cross sections at large P_T are the same in π^-p and π⁺p collisions. They decrease faster with P_T in pp collisions than in πp collisions
