Query: Unitary coupled channel analysis of the $\Lambda(1520)$ resonance   We study the $\Lambda(1520)$ resonance in a coupled channel approach
involving the $\pi\Sigma(1385)$, $K\Xi(1530)$, $\bar{K}N$ and $\pi\Sigma$
channels. Implementing unitarity in coupled channels, we make an analysis of
the relative importance of the different mechanisms which contribute to the
dynamical structure of this resonance. From experimental information on some
partial wave amplitudes and constraints imposed by unitarity, we get a
comprehensive description of the amplitudes and hence the couplings to the
different channels. We test these amplitudes in different reactions like
$K^-p\to\Lambda\pi\pi$, $\gamma p\to K^+K^-p$, $\gamma p\to
K^+\pi^0\pi^0\Lambda$ and $\pi^- p\to K^0 K^-p$ and find a fair agreement with
the experimental data.
