Interactive fields in QFT - the φ^3 example

In summary, the conversation discusses the need for resources on the topic of \phi^3 interactive field in quantum field theory. The main reference mentioned is Ryder's QFT, which only covers the \phi^4 interaction. Other similar textbooks such as Peskin's, Brown's, and Sterman's also do not cover \phi^3 theory. The individual is currently deriving point functions and wants to compare their results with the correct ones. It is suggested to look at a draft of a QFT book by Srednicki and also mentioned that Sterman's QFT book and Muta's QCD book cover \phi^3 theory.

Does anybody knows a textbook, a paper or any lecture notes that discusses the [tex]\phi^3[/tex] interactive field? I use as main reference Ryder's QFT, which discusses only the [tex]\phi^4[/tex] interaction. And most similar textbooks (like Peskin's, Brown's etc.) do so.

I have derived the point functions and currently trying to renormalize the [tex]\phi^3[/tex] theory, so I'd like to compare my results with the right ones. Thanx!

It's discussed in many books. Take a look at this draft of a QFT book by Srednicki:

Sterman's QFT book also discusses phi-3 theory, so does Muta's QCD book.

Thanx a lot!
 

1. What is QFT and how does it relate to the φ^3 example?

Quantum Field Theory (QFT) is a theoretical framework that combines the principles of quantum mechanics and special relativity to describe the behavior of subatomic particles. The φ^3 example is a specific model within QFT that illustrates how the theory works and allows for calculations and predictions to be made.

2. What are interactive fields in QFT?

Interactive fields in QFT refer to the fundamental fields that represent the building blocks of matter and their interactions with each other. These fields are described by mathematical equations and are responsible for the creation and annihilation of particles.

3. How does the φ^3 example illustrate the concept of renormalization in QFT?

Renormalization is a technique used in QFT to remove infinities from calculations and make them more physically meaningful. In the φ^3 example, the interaction between particles can lead to infinite values, but through renormalization, these values can be adjusted to match experimental observations.

4. Can the φ^3 example be applied to other fields in QFT?

Yes, the φ^3 example is a simplified model that can be extended to other fields in QFT, such as the electromagnetic field. This allows for a deeper understanding of the theory and its applications in various areas of physics.

5. How does the study of interactive fields in QFT impact our understanding of the universe?

By studying interactive fields in QFT, we can gain insight into the fundamental forces and particles that make up our universe. This allows us to better understand the behavior of matter at a subatomic level and make predictions about the behavior of complex systems, such as the formation of stars and galaxies.
