New narrow LHCb pentaquarks as lowest antiquark-diquark-diquark systems

The antiquark-diquark-diquark model describes pentaquark states both in terms of quarks and hadrons. We discuss pentaquark states with hidden charm $P(\bar{c} cuud)$ discovered in the $J/\varPsi p$ spectrum by the LHCb collaboration. We consider three pentaquark states as members of the lowest (S-wa...

description The antiquark-diquark-diquark model describes pentaquark states both in terms of quarks and hadrons. We discuss pentaquark states with hidden charm $P(\bar{c} cuud)$ discovered in the $J/\varPsi p$ spectrum by the LHCb collaboration. We consider three pentaquark states as members of the lowest (S-wave) multiplet and discuss the mass splitting scheme. The latest LHCb data for pentaquarks with hidden charm provide an opportunity to make an assumption about the diquark content of the pentaquark states. We give a classification for the LHCb pentaquarks and define recombination channels for these states.
