Photon and Nucleon Induced Production of Θ+
Abstract
We investigate Θ+ production via photon and nucleon induced reactions. We observe that the positive parity Θ+ production provides about ten times larger total cross sections than those of the negative parity one in both photon and nucleon induced reactions due to P-wave enhancement of the KNΘ vertex. We also consider the model independent method in the nucleon induced reaction to determine the parity of Θ+ and show clearly distinguishable signals for the two parities.
