    "abstract": "Photoproduction of the Theta+ pentaquark on the proton is analyzed by using\nan isobar and a Regge models. The difference in the calculated total cross\nsection is found to be more than two orders of magnitude for a hadronic form\nfactor cut-off Lambda \u003e 1 GeV. Comparable results would be obtained for 0.6 \u003c\nLambda \u003c 0.8 GeV. We also calculate contribution of the Theta+ photoproduction\nto the GDH integral. By comparing with the current phenomenological\ncalculation, it is found that the GDH sum rule favors the result obtained from\nRegge approach and isobar model with small Lambda.",
