Search for Pentaquarks in the Hadronic Decays of the Z Boson with the DELPHI detector at LEP

The quark model does not exclude pentaquark systems. Recent controversial evidence for such states has been published, in particular for a strange pentaquark Q 1540 , for a double-strange state called X 1862 and for a charmed state Qc 3100 0. Such states should be produced in e e annihilations in Z...

description The quark model does not exclude pentaquark systems. Recent controversial evidence for such states has been published, in particular for a strange pentaquark Q 1540 , for a double-strange state called X 1862 and for a charmed state Qc 3100 0. Such states should be produced in e e annihilations in Z decays. In this paper a search for pentaquarks using the DELPHI detector is described. Preliminary upper limits at 95% C.L. are set on the production rates per Z decay of such particles and their charge-conjugate state.
