On internal structure of the heavy-light mesons

Abstract

We compute the radial distributions of the vector and axial charge density as well as of the matter density in the heavy-light mesons on the lattice. The results for the lowest lying static heavy-light mesons and their first excited counterparts are obtained with Nf=2 dynamical quarks of Wilson (Clover) type and with the various improved static heavy quark actions. From these distributions we were able to compute the corresponding charges and slopes of the form factors (i.e. <r^2>). Those results are also presented, and briefly discussed too.
