Using large-scale real-time lattice simulations, we calculate the baryon asymmetry generated at a fast, cold electroweak symmetry breaking transition. CP-violation is provided by the leading effective bosonic term resulting from integrating out the fermions in the Minimal Standard Model at zero-temperature, and performing a covariant gradient expansion [A. Hernandez, T. Konstandin, and M. G. Schmidt, Nucl. Phys. B812, 290 (2009).]. This is an extension of the work presented in [A. Tranberg, A. Hernandez, T. Konstandin, and M. G. Schmidt, Phys. Lett. B 690, 207 (2010).]. The numerical implementation is described in detail, and we address issues specifically related to using this CP-violating term in the context of Cold Electroweak Baryogenesis.
