Title	Non-Abelian vortices and magnetic monopoles in 2 Higgs doublet model
Abstract	Electroweak strings and Nambu monopoles have been studiedin the literature, but they are not stable object because vacuumof the electroweak theory is topologically trivial.On the other hand, there exist topologically stable string andmonopoles in a two Higgs doublet model which is one of the simplestextension of the Higgs sector of the Standard model.In this talk I will first explain non-Abelian strings and then constructa magnetic monopole which is attached by non-Abelian strings.I also explain how the strings and monopoles are deformedwhen we vary the parameters in the two Higgs doublet model.
