Abstract: (arXiv)

In this work we present lattice calculations of the masses of P-wave mesons using Monte Carlo simulations. Our valence fermions are defined by the Wilson action. Our gauge fields are generated with both dynamical staggered fermions at a lattice coupling

\beta\equiv 6/g^2=5.6

for sea quark masses of

am_q=0.010

and 0.025, and in the quenched approximation at

\beta=6.0

. We present results for charm and charmonium spectroscopy and use them to compute the strong coupling constant

\alpha_s

. We compare our results to those of other recent lattice calculations and experiments.
