Query: Excited mesons from $N_f=2$ dynamical Clover Wilson lattices   We study mesons on the lattice with a special focus on excited states. For
that purpose we construct several quark sources with different spatial
smearings, including p-waves. These quark sources are then combined with the
appropiate Dirac structures to form meson interpolators of definite spin. We
use these operators to construct a cross correlation matrix from which we
extract ground and excited meson states using the variational method. For the
calculations we use gauge configurations with $N_f=2$ dynamical Clover Wilson
fermions provided by the CP-PACS collaboration. We show preliminary results for
pseudoscalar, scalar, vector and pseudovector mesons.
