Hybrid quarkonia with high statistics from NRQCD

Abstract We have studied the O(mv6) effects in NRQCD on the spectrum of heavy quarkonia and compare our results for different lattices (quenched and dynamical). We also report on an investigation into hybrid states within the framework of NRQCD. This suggests that the lowest lying hybrid is around the B ∗ B threshold and 3 standard deviation above the B B .
