Charge assignments in multiple-U(1) gauge theories

An evaluation of the analytic continuation by duality technique
In Nucl. Phys. B391 (1993) 127, the value of the oblique correction parameter S for walking technicolor theories was estimated using a technique called Analytic Continuation by Duality (ACD). We apply the ACD technique to ...
Detection in Hα of a Supershell Associated with W4
(IOP PUBLISHING LTD, 1997-01)
From H I observations, Normandeau, Taylor, & Dewdney have identified a possible Galactic chimney emanating from W4. We observed a 10 degrees diameter field centered on this region in the Her line using a CCD camera sensitive ...
Constraints on R-parity violating couplings from lepton universality
(American Physical Society, 2000-07-01)
We analyze the one loop corrections to leptonic W and Z decays in an R-parity violating extension to the minimal supersymmetric standard model. We find that lepton universality violation in the Z line-shape variables alone ...
A Water Maser Flare in W49N: Amplification by a Rotating Foreground Cloud
(IOP PUBLISHING LTD, 1998-12)
We monitored the 22 GHz H2O maser emission toward W49N from December 1989 through May 1990. During this period we observed an outburst in a component at -66.25 km s(-1). The flux density of the flaring component increased ...
