From Spectroscopy to the Strong Coupling Constant with Heavy Wilson Quarks
Abstract
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

for sea quark masses of

and 0.025, and in the quenched approximation at
β=6.0
. We present results for charm and charmonium spectroscopy and use them to compute the strong coupling constant

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