Unified gravity with electroweak through SU(2)xSU(2)xU(1)

In summary, the conversation discusses the symmetry SO(1,3)xU(1)=SU(2)xSU(2)xU(1) and the concept of local spontaneous broken symmetry. The field Φ acquires a vacuum expectation value of (0,v), resulting in a ΔL equation with three massive bosons, one massless photon, and two massless vector bosons. The conversation is about a personal theory, which is not allowed on the platform. The thread has been closed.

Consider symmetry SO(1,3)xU(1)=SU(2)xSU(2)xU(1) and puting a local spontaneous broken symmetry:
Φ→exp(iαaτa)exp(iαaτa)exp(i(β/2))Φ
The field Φ acquires vacuum expectation value: <Φ>=(0,v).
Then ΔL=½(0 v)(gCμaτa+gAμaτa+
½g'Bμ)2(0 v)T.Then we find out three massive boson,one massless photon and two massless vector boson corresponding with 8 components of gravitation field hμν
Is that correct?

Do you have a reference for this? PF does not allow discussion of personal theories.

What is unified gravity with electroweak through SU(2)xSU(2)xU(1)?

Unified gravity with electroweak through SU(2)xSU(2)xU(1) is a theoretical framework that attempts to combine the theory of gravity (described by Einstein's general relativity) with the theory of electroweak interactions (described by the Standard Model of particle physics) in a single, unified theory. This theory proposes that the fundamental forces of nature, including gravity, can be described by a single set of mathematical equations.

How does this theory differ from other attempts at unifying gravity with the other fundamental forces?

Unified gravity with electroweak through SU(2)xSU(2)xU(1) differs from other theories of unification in that it uses the mathematical framework of SU(2)xSU(2)xU(1) symmetry, which is a type of gauge symmetry. This allows for the incorporation of both gravity and electroweak interactions into a single theory, whereas other theories often struggle with incorporating gravity into the framework.

What evidence supports this theory?

Currently, there is no direct evidence for unified gravity with electroweak through SU(2)xSU(2)xU(1). However, this theory is supported by the fact that both gravity and electroweak interactions have been successfully described by separate theories, and it is a natural extension to try and unify them. Additionally, the mathematical framework of SU(2)xSU(2)xU(1) has been successful in describing other aspects of particle physics.

What are some potential implications of this theory?

If this theory is proven to be correct, it would have profound implications for our understanding of the fundamental forces of nature. It would provide a more complete and elegant description of the universe and could potentially lead to a better understanding of phenomena such as dark matter and dark energy.

What are the challenges in testing this theory?

One of the main challenges in testing this theory is that it makes predictions at energy scales far beyond what can currently be reached in experiments. As a result, it is difficult to directly test the theory. Additionally, there are other theories of unification that make similar predictions, so it is important to find ways to distinguish between them. Furthermore, there may be experimental limitations or technological barriers that prevent us from testing certain aspects of the theory.
