    "abstract": "We examine cross sections for the processes $\\gamma N\\to NK\\bar{K}$ in the\nframework of a phenomenological Lagrangian. We include contributions from\n$\\Lambda$ and $\\Sigma$ resonances up to spin 3/2, as well as those from an\nexotic $\\Theta^+$. We allow the $\\Theta^+$ to have spin 1/2 or 3/2, with either\npositive or negative parity in each case. We also allow the state to be either\nisovector or isoscalar. We find that the scenario that most closely matches\nobservations at Jefferson Laboratory requires a moderately large coupling of\nthe $\\Theta^+$ to $NK^*$.",
