We present heavy-meson spectrum results obtained using the Oktay-Kronfeld (OK) action on MILC asqtad lattices. The OK action was designed to improve the heavy-quark action of the Fermilab formulation, such that heavy-quark discretization errors are reduced. The OK action includes dimension-6 and -7 operators necessary for tree-level matching to QCD through order O(Λ 3 /m 3 Q ) for heavy-light mesons and O(v 6 ) for quarkonium, or, equivalently, through O(a 2 ) with some O(a 3 ) terms withdoi:10.22323/1.214.0097 fatcat:exiswwovljffniyoexp43jff24
