Four-quark and hybrid mixing in the light-quark vector sector

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The data one + e − annihilation are shown to be incompatible with an interpretation of the observed vector mesons as\(q\bar q\) excitations. It is necessary to consider mixing with some\(non - q\bar q\) system. Two specific models are considered: either four-quark states or hybrid states mixing with the conventional quark-antiquark excitations. Both models are compatible with the presente + e − annihilation data. It is possible to incorporate the 1.3 GeVJ PC=1−− state seen by LASS in the ππ channel in the four-quark model, but this is not possible with the hybrid model.
