“…Although still preliminary and not presented at this conference, the same pattern of hybrids is also found in a analysis of the B-meson system, on the same ensemble. These results also agree well with a recent determination of the spin-structure of bottomonium hybrids [15] using non-relativistic effective field theory and input from the lattice determination of the charmonium hybrids [5]. Looking in more detail at the operator overlaps in the lattice irreps in which hybrids have been identified and which were subduced from hybrid-like operators of the form…”

We present our first results on a direct computation of the complex in-medium heavy quark potential from realistic lattice QCD simulations. Ensembles with N τ = 12 from the HotQCD and TUMQCD collaboration offer unprecedented high statistics, those with N τ = 16 unprecedented time resolution, making possible a robust extraction of the real part from the spectral functions of Wilson line correlators. To this end we deploy a combination of a Bayesian reconstruction (BR method), as well as a Padé-like approximation. We corroborate findings made on less realistic lattices that Re[V] smoothly transitions from a confining to a screened behavior at high temperatures and its values lie close to the color singlet free energies. A finite value of the Im[V] is observed in the quark-gluon-plasma phase.

We report on the recent progress on the computation of the doubly heavy baryon spectrum in effective field theory. The effective field theory is built upon the heavy-quark mass and adiabatic expansions. The potentials can be expressed as NRQCD Wilson loops with operator insertions. These are nonperturbative objects and so far only the one corresponding to the static potential has been computed with lattice QCD. We review the proposal for a parametrization of the potentials based in an interpolation between the shortand long-distance regimes. The long-distance description is obtained with a newly proposed Effective String Theory which coincides with the previous ones for pure gluodynamics but it is extended to contain a fermion field. We show the doubly heavy baryon spectrum with hyperfine contributions obtained using these parametrizations for the hyperfine potentials.
