************************************************************** * * Paper : Diffractive Electroproduction of rho and phi Mesons * at HERA, DESY 09-093 * Reac : GAMMA* P --> RHO0 P(orY) * Caption : W dependence of the GAMMA*P cross sections for rho * meson production in four bins in t, for Q**2=3.3 GeV**2 * and Q**2=8.6 GeV**2. The notag (|t|<0.5 GeV**2) and * tag (|t|<3.0 GeV**2) samples are combined. * The overall normalisation uncertainty of 4% is not * included in the systematic errors. * ************************************************************** * * Q**2 t W Sigma stat syst+ syst - * 3.3 0.08 45 1451 51 124 -56 3.3 0.08 65 1677 66 123 -75 3.3 0.08 87 2030 82 173 -102 3.3 0.32 45 393 24 45 -29 3.3 0.32 65 433 30 48 -37 3.3 0.32 87 453 33 55 -44 3.3 0.69 45 95.1 9.4 16.1 -13.5 3.3 0.69 65 110 13 20 -17 3.3 0.69 87 124 19 22 -17 3.3 1.45 45 14.5 2.5 3.2 -2.7 3.3 1.45 65 9.0 1.8 2.7 -2.4 3.3 1.45 87 8.3 2.1 2.3 -2.2 * 8.6 0.08 65 261 14 23 -11 8.6 0.08 79 261 11 17 -10 8.6 0.08 104 320 14 22 -13 8.6 0.32 65 64.8 5.9 6.4 -3.8 8.6 0.32 79 72.8 5.3 6.0 -5.3 8.6 0.32 104 82.1 5.6 8.7 -5.9 8.6 0.69 65 16.5 1.7 3.1 -2.6 8.6 0.69 79 17.5 1.6 3.0 -2.5 8.6 0.69 104 17.3 1.7 3.6 -3.2 8.6 1.47 65 2.8 0.5 0.8 -0.8 8.6 1.47 79 1.5 0.3 0.9 -0.8 8.6 1.47 104 2.3 0.4 1.0 -0.9
