From spectroscopy to the strong coupling constant with heavy Wilson quarks.

In this work we present lattice calculations of the masses of {ital 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}{equivalent_to}6/{ital g}{sup 2}=5.6 for sea quark masses of {ital am}{sub {ital 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}{sub {ital s}}. We compare our results to those of other recent lattice calculations and experiments.
