Quarkonium Hybrids with Nonrelativistic Effective Field Theories
Matthias Berwein, Nora Brambilla, Jaume Tarrus Castella +1
We construct a nonrelativistic effective field theory description of heavy quarkonium hybrids from QCD. We identify the symmetries of the system made of a heavy quark, a heavy anti…

Heavy hybrids in pNRQCD
Jaume Tarrús Castellà
We report on the calculation of the Quarkonium Hybrid masses for the , and systems~\cite{hbrpaper}. A QCD analog of the Born-Oppenheimer approxim…

Long-range properties of bottomonium states
Nora Brambilla, Gastão Krein, Jaume Tarrús Castellà +1
In the framework of weakly-coupled pNRQCD, we derive, first, an analytical expression for the chromo-polarizability of -bottomonium states in agreement with previous determinat…
