In summary, QED and QCD are well-known theories in physics, but QFD (Quantum flavordynamics) is not a commonly used term. Electroweak Theory, which combines QED and QFD, is a more widely accepted concept. Quantum gravity theory is referred to as Quantum geometrodynamics (QGD) and there is also a theory called Quantum magnetodynamics (QMD), which is mentioned in at least one scientific journal. However, QFD and EWT are separate theories and are not usually joined together in the same way as QED and QCD.

QED = Quantum electrodynamics.
QCD = Quantum chromodynamics.

Is Electroweak Theory = Quantum flavordynamics (QFD)? Why does not anybody use the term "Quantum flavordynamics"?

What would a quantum gravity theory be called? "A quantum geometrodynamics" (QGD), perhaps?

Is there a separate theory called Quantum magnetodynamics (QMD)? I have seen that term at least in one scientifical journal.

Yes.

It just never caught on. The analogy between QED and QCD (both unbroken gauge theories with fermions and no scalars) is much clearer than it is between QED and QFD (a broken gauge theory with both fermions and scalars).

Hi again!

According to this http://hypertextbook.com/physics/modern/summary.shtml QFD and EWT are separate things:
"would be called quantum flavordynamics (QFD), but are usually joined with electromagnetism in electroweak theory (EWT)"
"the weak force was not described by an independent theory of what is sometimes informally called quantum flavordynamics (QFD)."
"The electroweak theory (EWT) of Glashow, Weinberg, and Salaam extended …

* quantum electrodynamics, which had been described, to include …
* quantum flavordynamics, which had not been described. "

1. What is Quantum Flavordynamics (QFD)?

Quantum Flavordynamics (QFD) is a theoretical framework that describes the interactions between subatomic particles, specifically the behavior and properties of different types of quarks and leptons.

2. How does QFD differ from Quantum Chromodynamics (QCD)?

QFD and QCD are both branches of quantum field theory that study the strong nuclear force, but QFD focuses on the interactions between different flavors of quarks and leptons, while QCD focuses on the interactions between quarks and gluons.

3. What is the significance of flavor in QFD?

In QFD, flavor refers to the different types of quarks and leptons, which are distinguished by their mass, charge, and other properties. The study of flavor in QFD allows us to understand the relationships and interactions between these particles.

4. How does QFD relate to the Standard Model of particle physics?

The Standard Model is a widely accepted theory that describes the fundamental particles and forces of the universe. QFD is a part of the Standard Model and provides a framework for understanding the behavior of quarks and leptons, which are the building blocks of matter.

5. What are some applications of QFD?

QFD has been used to make predictions about the behavior of subatomic particles, such as the existence of the top quark, which was later confirmed by experiments. It also has applications in understanding phenomena like neutrino oscillations and the behavior of matter in extreme conditions, such as in the early universe or inside neutron stars.
