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 -$t$.5 pages, 4 figuresNuclear TheoryIndication of anomalous exchange in exclusive charmonium photoproductiontext
