Sumario:Inclusive\pi^{0} production has been measured at the CERN pp collider, \sqrt{s}=540 GeV, for 90 degrees production angle and in a range of transverse moment between 1.5 and 4.5 GeV/c. The invariant production cross section is larger than that measured at \sqrt{s}=53 GeV for p-p collisions. The production of mu mesons and of direct photons is also investigated.
