Heavy Quarkonium Hybrids: Spectrum, Decay and Mixing

Understand

We present a largely model independent analysis of the lighter Heavy Quarkonium Hybrids based on the strong coupling regime of Potential Non-Relativistic QCD (pNRQCD).

• We calculate the spectrum at leading order, including the mixing of static hybrid states.
• We use potentials that fulfill the required short and long distance theoretical constraints and fit well the available lattice data.
• We argue that the decay width to the lower lying Heavy Quarkonia can be reliably estimated in some cases, and provide results for a selected set of decays.
