Azzeddine Benhamida, Lahouari Semlala
TL;DR
This paper explores the 600 resonance as a hybrid meson composed of quark, antiquark, and gluon, providing mass and decay width estimates within the Quark Model with Constituent Gluon framework.
Contribution
It introduces a novel interpretation of the 600 resonance as a hybrid meson in the Quark Model with Constituent Gluon, with specific mass and decay width predictions.
Findings
Mass estimate: 1.65 GeV with uncertainties
Decay width to rho-pi: approximately 0.28 GeV
Supports hybrid meson interpretation of the resonance
Abstract
The exotic J^{PC}= 1^{-+} resonance {\pi}_{1}(1600)is examined in the framework of the Quark Model with Constituent Gluon (QMCG). We report the possibility of interpreting that resonance as quark-antiquark-gluon hybrid meson, with a masse = 1.65+0.05-0.04 GeV and a rho-pi decay width = 0.28+0.14-0.09 GeV.
