A strategy for implementing non-perturbative renormalisation of heavy-light four-quark operators in the static approximation
We discuss the renormalisation properties of the complete set of $\Delta B = 2$ four-quark operators with the heavy quark treated in the static approximation. We elucidate the role of heavy quark symmetry and other symmetry transformations in constraining their mixing under renormalisation. By emplo...
