| Abstract | Based on data collected with the H1 detector at HERA in 2005, cross sections
for elastic rho photoproduction have been measured at momentum transfer
|t| < 0.58 GeV^2 and photon-proton centre-of-mass energies 20 < W < 90GeV. This data
has been combined with cross sections published previously by the Omega and
ZEUS collaborations in a global fit to determine the pomeron trajectory
alpha(t) in 13 bins of t from the W-dependence of the elastic rho production
cross section. |
