A one parameter representation for the Isgur-Wise function
M. G. Olsson, S. Veseli
Abstract
We use a 1S lattice QCD heavy-light wavefunction to generate a single parameter, model independent description of the Isgur-Wise function. Using recent data we find the zero-recoil slope to be ξ'(1)= -1.16 0.17, while the second derivative turns out to be ξ''(1)= 2.64 0.74.
