  • We report on the first measurement of exclusive single-photon muoproduction on the proton by COMPASS using 160 GeV/c polarized μ+ and μ− beams of the CERN SPS impinging on a liquid hydrogen target. We determine the dependence of the average of the measured μ+ and μ− cross sections for deeply virtual Compton scattering on the squared four-momentum transfer t from the initial to the final final proton. The slope B of the t-dependence is fitted with a single exponential function, which yields B… CONTINUE READING
