Determination of the velocity-dependent potentials at O(1/m2)

Presenter: Yoshiaki Koma — Numazu College of Technology

Y. Koma, M. Koma and H. Wittig

The velocity-dependent potentials are the parts of relativistic corrections to the static heavy quark potential at O(1/m2), which may affect the spectra and wavefunctions of heavy quarkonium. We investigate these corrections in SU(3) lattice gauge theory with the Polyakov loop correlation function by utilizing the multi-level algorithm and find remarkably clean signals.
