Within an effective field theory framework, we obtain an expression, with ${O(1/m}^{2})$ accuracy, for the energies of the gluonic excitations between heavy quarks, which holds beyond perturbation theory. For the singlet heavy-quark\char21{}antiquark energy, in particular, we also obtain an expression in terms of Wilson loops. This provides, twenty years after the seminal work of Eichten and Feinberg, the first complete expression for the heavy quarkonium potential up to ${O(1/m}^{2})$ for pure… 
Spectrum of the open QCD flux tube and its effective string description I: 3d static potential in SU(N = 2, 3)
A bstractWe perform a high precision measurement of the static qq¯$$ q\overline{q} $$ potential in three-dimensional SU(N) gauge theory with N = 2, 3 and compare the results to the potential obtained
Determination of ΛMS¯(nf=2) and analytic parametrization of the static quark-antiquark potential
While lattice QCD allows for reliable results at small momentum transfers (large quark separations), perturbative QCD is restricted to large momentum transfers (small quark separations). The latter
Phenomenology of the radiative E1 heavy quarkonium decay
We use the complete expression for the O(1/m^2) corrections to the quark-antiquark potential, where $m$ is the quark mass, derived from QCD in terms of Wilson loop expectation values, and a mapping,
Relativistic corrections to the static potential at O(1/m) and O(1/m^2)
We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m^2) velocity-dependent potentials, in SU(3) lattice gauge theory. They are important
Heavy quarkonium electric dipole transitions in non-relativistic quantum field theory
In this work we use the low-energy EFT called potential non-relativistic QCD (pNRQCD) to calculate the partial decay width of different $b\bar{b}$-states undergoing an electric dipole transition at
MS renormalization of S-wave quarkonium wavefunctions at the origin
We compute $S$-wave quarkonium wavefunctions at the origin in the $\overline{\rm MS}$ scheme based on nonrelativistic effective field theories. We include the effects of nonperturbative long-distance
Determination of the relativistic corrections to the static inter-quark potential from lattice QCD
We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m2) spin-dependent potentials, in SU(3) lattice gauge theory. Utilizing the multilevel
Nonperturbative determination of the QCD potential at O(1/m).
The relativistic correction to the QCD static interquark potential at O(1/m) is investigated nonperturbatively for the first time by using lattice Monte Carlo QCD simulations. The correction is found
Scaling study of the relativistic corrections to the static potential
The relativistic corrections to the static potential, i.e. the O(1/m) correction, the O(1/m^2) spin-dependent and momentum-dependent corrections are investigated in SU(3) lattice gauge theory. These
Precision computation of hybrid static potentials in SU(3) lattice gauge theory
We perform a precision computation of hybrid static potentials with quantum numbers $\Lambda_\eta^\epsilon = \Sigma_g^-,\Sigma_u^+,\Sigma_u^-,\Pi_g,\Pi_u,\Delta_g,\Delta_u$ using SU(3) lattice gauge
