| dc.description | We study leptonic and semi-leptonic decays of D and B mesons. Use of the Hopping Parameter Expansion (HPE) for two-point functions allows us continuously to vary the pseudoscalar mass from below m_D up towards m_B. We compute the pseudoscalar decay constants f_D and f_B, and observe consistency with the value calculated in the static limit. {}From the measurement of three-point functions we compute the matrix element relevant to the decay \bar B -> D l \bar nu_l and extract the Isgur-Wise function xi(v.v'). The HPE enables us freely to vary the initial state pseudoscalar mass at constant v.v', and we investigate the 1/m_Q corrections to the heavy-quark limit. | |
