We find that available data on J/Ψ photoproduction at |t|≥1 GeV are energy independent over the range 22≤√(s)≤170 GeV and show a very soft t dependence. Through a systematic analysis of the data we detect a new trajectory, which manifests itself at threshold and is energy independent. The trajectory couples to the axial form factor of the nucleon and can reproduce the J/Ψ exclusive photoproduction data at large -t.
