The Polyakov loop at next-to-next-to leading order
Matthias Berwein, Nora Brambilla, Peter Petreczky +1
We calculate the next-to-next-to-leading correction to the expectation value of the Polyakov loop or equivalently to the free energy of a static charge. This correction is of order…

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…
