Density distributions in the $B$ meson

Résumé

We report on a two-flavor lattice QCD study of the axial, charge, and matter distributions of the B meson and its first radial excitation. As our framework is the static limit of heavy quark effective theory (HQET), taking their Fourier transform gives access to several form factors at the kinematical point q2=0 while our previous computations in that framework were performed at qmax2. Moreover, they provide some useful information on the nature of an excited state, i.e., a radial excitation of a quark-antiquark bound state or a multihadron state.
