ABSTRACT
Scalar fields are a central element of the unified electroweak theory, in that they make possible the spontaneous breaking of the S U ( 2 ) L ⊗ U ( 1 ) Y $ SU(2)_L\otimes U(1)_Y $ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315369723/48d43afe-85b0-4e2b-a932-df2bd1af07be/content/inline-math18_1855.tif"/> gauge symmetry required to give rise to the masses of quarks, leptons and vector fields, cf. [2].
