Heavy Quark Phenomenology from Lattice QCD
  Recent results relevant for the B-physics phenomenology, obtained from lattice QCD simulations by the APE Collaboration, are reviewed. This includes the B0-B0bar mixing amplitude, B-> pi semileptonic decay and the relative width difference of B0_s mesons, $(\Delta \Gamma/\Gamma)_{B_s}$.
