in eclipse and breaking dawn they have a baby and go skinny dipping.

The Higgs field has a non-trivial self-interaction, which leads to spontaneous symmetry breaking: in the lowest energy state the symmetry of the potential (which includes the gauge symmetry) is broken by the condensate.

In the simplest example, the spontaneously broken field is described by a scalar field theory. In physics, one way of seeing spontaneous symmetry breaking is through the use of Lagrangians. Lagrangians, which essentially dictate how a system will behave, can be defined in potential terms:

L = du(f)du(f) - V(f).

It is in this potential term V(f) that the action of symmetry breaking occurs. The potential graph of this function has the look and appearance of a Mexican hat.

The book Breaking Dawn is probably the one you are talking about. The book does have several adult messages but not really too bad. The messages are implied but the subject does not come out in full.
