We then show that the electroweak phase\ntransition is strongly first-order, the dark matter relic density takes the\ndesired value Ω_DMh^2 ∼ 0.11, and the constraints from\ndirect detection experiments are respected only if m_s'≡ m_DM≳ 4.5 TeV. The model also puts a lower bound on the scalon mass, m_s\n≳ 200 GeV.", 'mimetype': 'text/plain', 'lang': 'en'}
