To proceed, we decompose the complex field into radial and phase oscillations as

(3.56)

In this case, the derivatives of ϕ() will generate additional terms in the resulting Lagrangian; however, these can be absorbed into a field redefinition (gauge transformation)

(3.57)

Combining the expansion with this gauge transformation, one finds

(3.58)

The particle spectrum of this theory contains:

A massive scalar field ‘H’ (Higgs field) of mass [second term in (3.58)].

A Goldstone field that has been ‘absorbed’ or ‘eaten’ by [no terms involving ξ or remain in (3.58)].
