Abstract
Proceeding from WKB quantization conditions, we derive a semiclassical expression for the current of fermions scattered off a propagating bubble wall in the presence of longitudinal gauge field. It agrees with the expression used by Nasser and Turok in semiclassical analysis of instability of electroweak bubble walls with respect to longitudinal condensation. We discuss the resulting dispersion relation for longitudinal field and show that light species are important for the analysis of stability, because of their large contribution to plasma frequency.
