A pipeline

1. Choose your model (e.g. SM, xSM, 2HDM, ...)
2. Dim. red. model
   Kajantie et al.
3. Phase diagram ($\alpha_{T_*}$, $T_*$);
   lattice: Kajantie et al.
4. Nucleation rate ($\beta$);
   lattice: Moore and Rummukainen
5. Wall velocities ($v_\text{wall}$)
   Moore and Prokopec; Kozaczuk
6. GW power spectrum $\Omega_\mathrm{gw}$
7. Sphaleron rate

Very leaky, even for SM!

Update to LISA CosWG report

[arXiv:1512.06239]

• Coming soon! 😅
• In 'beta', online GW plotting tool PTPlot: ptplot.org

What I am thinking about

• Turbulence
  • MHD or no MHD?
  • Timescales $H_* R_*/\overline{U}_\mathrm{f} \sim 1$, sound waves and turbulence?
  • More simulations needed?
  
  
• Complementarity of GW signal and BG [next week!]
  • Competing wall velocity dependence of BG and GWs?
  • Sphaleron rates in extended models?
  
  
• The best possible determinations for xSM, 2HDM, $\Sigma$SM, ...
  • What is the phase diagram?
  • Nonperturbative nucleation rates?
