FROM SPECTROSCOPY TO THE STRONG-COUPLING CONSTANT WITH HEAVY WILSON QUARKS

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 β6/g2=5.6 for sea quark masses of amq=0.010 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 αs. We compare our results to those of other recent lattice calculations and experiments. © 1995 The American Physical Society.
