3. Phenomenological applications of non-perturbative heavy quark effective theory

We briefly review the strategy to perform non-perturbative heavy quark effective theory computations and we specialize to the case of the b quark mass which has been recently computed including the 1/m term. We consider another phenomenologically relevant quantity where this strategy could be applied, the B_B parameter which is related to the neutral B meson mass difference.

4. Towards the lattice measurement of f_Bs at O(1/m_b) in Heavy Quark Effective Theory

We will present a strategy to extract from a lattice computation the decay constant f_Bs. It involves a non pertubative matching of QCD with Heavy Quark Effective Theory including 1/m_b corrections, which is done in a very small physical volume. After a non perturbative evolution of observables in the effective theory to larger volumes, the decay constant is determined from simulations...
