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 ...
Energies and residues of the nucleon resonances N(1535) and N(1650)
(American Physical Society, 1998-12)
We extract pole positions for the N(1535) and N(1650) resonances using two different models. The positions are determined from fits to different subsets of the existing pi N --> pi N, pi N --> eta N, and gamma p --> eta p ...
Photogeneration action spectroscopy of neutral and charged excitations in films of a ladder-type poly(para-phenylene)
(American Physical Society, 1999-04-19)
The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both tripler and polaron action spectra show, ...

Infrared activity in the Aurivillius layered ferroelectric SrBi2Ta2O9
(American Physical Society, 1998-03-01)
Experimental studies were carried out on infrared-active phonons in the Aurivillius ferroelectric SrBi2Ta2O9 (SBT), using reflectivity measurements (down to 200 cm(-1)) and transmission measurements (down to 100 cm(-1)) ...
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). ...

Constraints on top-color assisted technicolor models from vertex corrections
