#### Constraints on top-color assisted technicolor models from vertex corrections

(American Physical Soc, 1999-07-01)

#### Charge assignments in multiple-U(1) gauge theories

(American Physical Soc, 1999-12-01)

#### Monte Carlo simulation calculation of the critical coupling constant for two-dimensional continuum phi(4) theory

(American Physical Society, 1998-10)

We perform a Monte Carlo simulation calculation of the critical coupling constant for the continuum two-dimensional (lambda/4) phi(4) theory. The critical coupling constant we obtain is [lambda/mu(2)](crit) = 10.26(-.04)(+.08). ...

#### Predictions of m(b)/m(tau) and m(t) in an asymptotically nonfree theory

(Amer Physical Soc, 1997-08-01)

#### ACD estimation of the S-parameter revisited

(Elsevier Science Bv, 1997-05-29)

#### Choice of dispersion relation to calculate the QCD correction to Gamma(H->l(+)l(-))

(American Physical Soc, 1996-02-01)

We use the Operator Product Expansion (OPE) of quark vacuum polarization functions to show that the dispersion relation of Kniehl and Sirlin will yield the correct result to all orders in αs when applied to the QCD correction ...

#### Charge assignments in multiple-U(1) gauge theories

(American Physical Society, 1999-12-01)

We discuss the choice of gauge field basis in multiple-U(1) gauge theories. We find that there is a preferred basis, specified by the charge orthogonality condition, in which the U(1) gauge fields do not mix under one-loop ...

#### Delta isobar masses, large N-c relations, and the quark model

(American Physical Society, 1999-01-01)

Motivated by recent remarks on the Delta(+) mass and comparisons between the quark model and relations based on large-iri, with perturbative flavor breaking, two sets of Delta masses consistent with these constraints are ...

#### OBLIQUE CORRECTIONS TO THE W-WIDTH

(American Physical Soc, 1994-02-01)

#### REMARKS ON THE DISPERSION-RELATIONS USED TO CALCULATE DELTA-RHO

(American Physical Soc, 1995-06-01)

We use the operator product expansion (OPE) to show that nonperturbative QCD corrections to Δρ can be calculated using unsubtracted dispersion relations for either the transverse or the longitudinal vacuum polarization ...
