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

Abstract:

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 (1860)- -; and for a charmed state, the Θc (3100)0. If confirmed, a full pentaquark family might exist; such pentaquark states could be produced in e+ e- annihilations near the Z energy. In this Letter...
