We report on a measurement of hard exclusive pi(0) muoproduction on the proton by COMPASS using 160GeV/cpolarised mu+ and mu- beams of the CERN SPS impinging on a liquid hydrogen target. From the average of the measured mu+ and mu- cross sections, the virtual-photon proton cross section is determined as a function of the squared four-momentum transfer between initial and final proton in the range 0.08 (GeV/c)(2)

Abstract
We report on a measurement of hard exclusive pi(0) muoproduction on the proton by COMPASS using 160GeV/cpolarised mu+ and mu- beams of the CERN SPS impinging on a liquid hydrogen target. From the average of the measured mu+ and mu- cross sections, the virtual-photon proton cross section is determined as a function of the squared four-momentum transfer between initial and final proton in the range 0.08 (GeV/c)(2)
