New physics from Higgs self-coupling measurement
  Radiative correction to the triple Higgs boson coupling is studied in the two Higgs doublet model in connection with the electroweak baryogenesis. It is shown that the one loop correction is large enough to be identified in future linear collider experiments, if the baryon number of the Universe is generated at the first order electroweak phase transition.
