    "abstract": "We analyze the possibility to produce an intermediate Theta^+ via a\nKN-\u003e\\Theta+ formation process in gamma D-\u003e pK^- X (X=nK^+,pK^0) reactions at\nsome specific kinematical conditions, in which a pK^- pair is knocked out in\nthe forward direction and its invariant mass is close to the mass of\nLambda(1520). The \\Theta^+ signal may appear in the [\\gamma D,pK^-] missing\nmass distribution. The ratio of the signal (cross section at the \\Theta^+ peak\nposition) to the smooth background processes varies from 0.7 to 2.5 depending\non the spin and parity of Theta+, and it decreases correspondingly if the pK^-\ninvariant mass is outside of the Lambda(1520)-resonance region. We analyze the\nrecent CLAS search for the Theta+ in the gamma D -\u003epK^-nK^+ reaction and show\nthat the conditions of this experiment greatly reduce the Theta+ formation\nprocess making it difficult to extract a Theta+ peak from the data.",
