Search for pentaquarks in the hadronic decays of the Z boson with the DELPHI detector at LEP

Search for pentaquarks in the hadronic decays of the Z boson with the DELPHI detector at LEP

The quark model does not exclude states composed of more than three quarks, like pentaquark systems. Controversial evidence for such states has been published in the last years, in particular: for a strange pentaquark Θ (1540)+; for a double-strange state, the Ξ (1862)- -, subsequently called Φ (186...
