Description
The state pi1(1600) has exotic quantum numbers 1^-+ and is rightfully treated as a hybrid (quark-antiquark-gluon) candidate. Recently, the eta1(1855) has been experimentally discovered. It is then natural to expect that a whole nonet of hybrid states must exist: besides the two states above, a kaonic hybrid and a light eta1 hybrid should exist as well. Predictions and postdictions for the strong (PLB.B 834 (2022) 137478 ) and radiative (2302.07687) decays of hybrids are outlined. This may be useful for the future search of the yet undiscovered light isoscalar and kaonic hybrid states. The production of the in J/Psi decays is also discussed.
