  We derive the kinetic equation for fermions and antifermions interacting with
a planar Higgs bubble wall during the electroweak phase transition using the
`evenisation' procedure and the Wigner formalism for a Lagrangian with the
phase of the complex fermion mass rotated away. We obtain the energy, velocity
and force for the particles in the presence of the Higgs bubble wall. Our
results using both methods are in agreement. This indicates the robustness of
evenisation as a method to study quantum corrections to the velocity and force
for particles in the Higgs wall during the electroweak phase transition. We
also derive the transport equations from the zeroth and first moment of the
kinetic equation.
