    "abstract": "We study the gamma p ---\u003e K^+ Lambda(1405) reaction at energies close to\nthreshold using a chiral unitary model where the resonance is generated\ndynamically from K^-p interaction with other channels constructed from the\noctets of baryons and mesons. Predictions are made for cross sections into\nseveral channels and it is shown that the detection of the K^+ is sufficient to\ndetermine the shape and strength of the Lambda(1405) resonance. The\ndetermination of the resonance properties in nuclei requires instead the\ndetection of the resonance decay channels. Pauli blocking effects on the\nresonance, which have been shown to be very important for the resonance at rest\nin the nucleus, are irrelevant here where the resonance is produced with a\nlarge momentum. The nuclear modifications here would thus offer information on\nthe resonance and K^- nucleus dynamics complementary to the one offered so far\nby K^- atoms.",
