| Abstract | Using a sample of more than 240000 events taken with the H1 detector
at HERA in 2005, a new measurement of exclusive
r0 photoproduction in the kinematic range 20 < W < 90 GeV
and |t| < 3 GeV2 is performed.
From the measurement of
the W dependence of this process in eight bins of t,
the Pomeron trajectory aPom (t) can be extracted
for the first time from the data of a single experiment.
The result is
aPom (t) = {1.093 ± 0.003 (stat.) +0.008 -0.007 (syst.)} + {0.116 ± 0.027 (stat.) +0.036 -0.046 (syst.)} GeV-2 × t. |
