Soft dynamics in heavy-light mesons

We compute the radial distributions of the scalar, vector and axial charge density in the heavy-light mesons. We present the results obtained for both the lowest lying static heavy-light mesons as well as for their nearest excitations, with $N_f=2$ dynamical quarks of Wilson (Clover) type. We used various improvements of the static heavy-quark actions. From these distributions we were able to compute the corresponding charges and their radii $< r^2>$, the results of which are also presented.
