Pentaquarks and resonances in the $pJ/\psi$ spectrum

We consider exotic baryons with hidden charm as antiquark-diquark-diquark\ncomposite systems. Spin and isospin structure of such exotic states is given\nand masses are estimated. The data for production of pentaquarks in the\nreaction $\\Lambda_b\\to K^-p J/\\psi$ are discussed. We suggest that the ... View More
