Calculation of f_B and the ``Isgur-Wise Function'' using a non-perturbatively improved fermion action
UKQCD Collaboration: David Richards (University of Edinburgh)🇬🇧
Abstract
We present a calculation of f_B and of the form factors for the semi-leptonic decay B -> D l nu in the quenched approximation to QCD. Results are generated on lattices at beta = 6.2, using an O(a)-improved fermion action, with the clover coefficient determined non-perturbatively.
