Relativistic corrections to the static potential from generalized Wilson loops at finite flow time

We present results from an ongoing project concerned with the computation of \(\mathcal{O}(1/m_Q)\) and \(\mathcal{O}(1/m_Q^2)\) relativistic corrections to the static potential. These corrections are extracted from Wilson loops with two chromo-field insertions. We use gradient flow, which allows to...

Description
Summary:We present results from an ongoing project concerned with the computation of \(\mathcal{O}(1/m_Q)\) and \(\mathcal{O}(1/m_Q^2)\) relativistic corrections to the static potential. These corrections are extracted from Wilson loops with two chromo-field insertions. We use gradient flow, which allows to renormalize the inserted fields and leads to a significantly improved signal-to-noise ratio, providing access to loops with large spatial and temporal extents.
