Reply to Boglione and Pennington
W. Lee, D. Weingarten
In a recent article we presented an argument which, we believe, shows to be incorrect an estimate, by Boglione and Pennington, of corrections to the valence (quenched) approximatio…
Scalar Quarkonium Masses and Mixing with the Lightest Scalar Glueball
W. Lee, D. Weingarten
We evaluate the continuum limit of the valence (quenched) approximation to the mass of the lightest scalar quarkonium state for a range of different quark masses and to the mixing…
Continuum Limit of Scalar Masses and Mixing Energies
W. Lee, D. Weingarten
We evaluate the continuum limit of the valence approximation to the mass of scalar quarkonium and to the scalar quarkonium-glueball mixing energy for a range of different quark mas…
Coupling Constant and Quark Loop Expansion for Corrections to the Valence Approximation
W. Lee, D. Weingarten
For full QCD vacuum expectation values we construct an expansion in quark loop count and in powers of a coupling constant. The leading term in this expansion is the valence (quench…
Scalar Quarkonium Masses and Mixing with the Lightest Scalar Glueball
W. Lee, D. Weingarten
We evaluate the continuum limit of the valence (quenched) approximation to the mass of the lightest scalar quarkonium state, for a range of different quark masses, and to the mixin…
Improved Error Estimate for the Valence Approximation
W. Lee, D. Weingarten
We construct a systematic mean-field-improved coupling constant and quark loop expansion for corrections to the valence (quenched) approximation to vacuum expectation values in the…
