Abstract:
In this thesis I study semi-leptonic decays of mesons containing one heavy and one light quark. I describe the necessary theoretical tools of Lattice Gauge Theory and of Heavy Quark Effective Theory. The six form factors describing the semi-leptonic decays are extracted from a lattice gauge theory calculation. The dependence of the form factors on the masses of the heavy and light quarks is studied. The results are compared to the predictions of Heavy Quark Symmetry and corrections to the exact symmetry limit of infinitely heavy quarks are analysed. The slope of the Isgur-Wise function is extracted from the lattice simulation and it is used to extract the Cabbibo-Kobayashi-Maskawa matrix element Vcb. The results are compared to those of other authors where possible.
