Operators emphasizing quark or gluon degrees of freedom provide different insights.
Results contribute to understanding the mechanisms of hadronic interactions.
Abstract
A system of two static quarks, at fixed distances r, and two light quarks is studied on an anisotropic lattice. Excitations by operators emphasizing quark or gluon degrees of freedom are examined. The maximum entropy method is applied in the spectral analysis. These simulations ultimately aim at learning about mechanisms of hadronic interaction.
