Where does energy come from in QFT?

Click For Summary
SUMMARY

The discussion centers on the origin of energy in Quantum Field Theory (QFT) during particle creation, specifically in the context of beta decay. It is established that the energy required to create excitations in the electron field comes from the W boson involved in the decay process. This interaction illustrates the fundamental principles of energy transfer and particle formation within QFT, emphasizing the role of gauge bosons in mediating these processes.

Homework Statement
The origin of energy in the creation of elementary particles
Relevant Equations
QFT
When we say energy is applied to that field to create an excitation which is a particle, where does that energy come from and how is it applied? For example on beta decay where a new electron is formed, where does the energy come from the create an excitement in the electron field?
