Just as for the strong force, thisthe conclusion that the transition is a crossover assumes the minimal scenario, and is modified by the presence of additional fields or particles. Particle physics models which account for [[dark matter]] or which lead to successful [[baryogenesis]] may predict a strongly first-order electroweak phase transition.<ref name="Cline2013">{{cite journal |last1=Cline |first1=James |last2=Kainulainen |first2=Kimmo |title=Electroweak baryogenesis and dark matter from a singlet Higgs |journal=JCAP |date=2013 |volume=01 |pages=012 |doi=10.1088/1475-7516/2013/01/012|arxiv=1210.4196}}</ref>
