$B_c$ and $\hat{I}\yen$ Spectra from Lattice NRQCD - Results at ${\hat{I}}^2$ = 5.7

Abstract

We update our results for the heavy-heavy spectrum at ${\hat{I}}^2$ = 5.7, using NRQCD. This includes a scaling comparison with the $\hat{I}\yen$ spectrum at ${\hat{I}}^2$ = 6.0 and first lattice predictions for the $B_c$ spectrum.
