Test of QCD indū→W − γg, the radiation amplitude zero and the magnetic moment of theW boson
(1985)
We have calculated the differential cross-section for the processdū→W − γg (Jet). It is found that, although the radiation amplitude zero, which occurs for the lowest-order processdū→W −γ, is spoiled, there remains a very ...
One-loop vacuum polarization in the nonlinear Rξ gauge
(1985)
In the nonlinear Rξ gauge the one-loop contributions to the dynamical-gauge-field vacuum polarization are found to be separately transverse even in a spontaneously broken theory. Moreover, the theorems of DeWitt and Kallosh ...
What is the Charge Radius of the Neutrino? An Investigation in the Background Field Gauge
(1985)
The one loop contributions to the neutrino charge radius are calculated in the background field gauge. The large logarithm term is found to be gauge invariant while other terms prove to be highly gauge dependent. It is ...
