    "abstract": "We have carried a theoretical study of the K^- p\\to M B \\gamma reaction with\nM B = K^-p, \\bar{K}^0 n, \\pi^- \\Sigma^+, \\pi^+ \\Sigma^-, \\pi^0 \\Sigma^0, \\pi^0\n\\Lambda, for K^- lab. momenta between 200 and 500 MeV/c, using a chiral unitary\napproach for the strong K^-p interaction with its coupled channels. The\n\\Lambda(1405) resonance, which is generated dynamically in this approach, shows\nup clearly in the d\\sigma/dM_I spectrum, providing new tests for chiral\nsymmetry and the unitary approach, as well as information regarding the nature\nof the resonance. The photon detection alone, summing all channels, is shown to\nreproduce quite accurately the strength and shape of the \\Lambda(1405)\nresonance. Analogous reactions in nuclei can provide much information on the\nproperties of this resonance in a nuclear medium.",
