pNRQCD: review of selected results
Antonio Vairo
I review and discuss a selected sample of recent results in pNRQCD.
The Role of the QCD Vacuum in the Heavy-Quark Bound State Dynamics
N. Brambilla, A. Vairo
The effective field theory approach allows a rigorous disentangling of high and low energy effects in the heavy quarkonium dynamics. Focusing in particular on the spectrum, we desc…
Quarkonium: an effective field theory approach
Nora Brambilla, Antonio Vairo
We discuss heavy quarkonium in the framework of pNRQCD, a QCD effective theory appropriate for the study of heavy quark bound systems.
Quark Confinement and the Hadron Spectrum
Nora Brambilla, Antonio Vairo
These lectures contain an introduction to the following topics: 1) Phenomenology of the hadron spectrum; 2) The static Wilson loop in perturbative and in lattice QCD. Confinement a…
Nonperturbative interaction in qqbar bound states
N. Brambilla, A. Vairo
We report about recent progress in the treatment of bound states in QCD.
The quark-antiquark Wilson loop formalism in the NRQCD power counting scheme
Antonio Vairo
The quark-antiquark interaction from the NRQCD Lagrangian is studied in the Wilson loop formalism.
