Does ''Higgs sector'' mean there are many Higgs particle types?

In summary, the conversation discusses the concept of the "Higgs sector" in relation to the number of Higgs particles in the theory of electroweak interaction. The term is used to describe both models with multiple Higgs bosons and the model with just one Higgs particle. The role of custodial symmetry (SU(2)) in the Standard Model is also briefly mentioned.

Please teach me this:
Does ''Higgs sector'' mean there are many Higgs particle types?Does custodial SU(2) symmetry using mean maybe there is a theory of electroweak interaction more complex than theory of single Higgs scalar?
Thank you in advance.

I mean there may be many type of Higgs boson in the theory of electroweak interaction because they say '' Higgs sector''.
 
  • #3
There are models with multiple Higgs bosons (most notably supersymmetry), but I heard the term "Higgs sector" for the model with just one Higgs particle, too. The model of EW symmetry breaking is complex enough to call that part "Higgs sector".

Please tell me more some details of the role of custodial symmetry(SU(2)) in Standard Model extent.

If you look for an introduction to the Higgs mechanism, read a book or lecture script.
 

1. What is the Higgs sector in particle physics?

The Higgs sector is a theoretical concept in particle physics that describes the interactions between particles and the Higgs field. It is a crucial component of the Standard Model of particle physics.

2. How many Higgs particles are there in the Higgs sector?

According to the Standard Model, there is only one Higgs particle, known as the Higgs boson. However, some theories propose the existence of multiple Higgs particles, which would result in a more complex Higgs sector.

3. What is the significance of multiple Higgs particles in the Higgs sector?

The existence of multiple Higgs particles would challenge the current understanding of the Higgs mechanism and could potentially explain some of the unresolved questions in particle physics, such as the origin of dark matter.

4. How can we detect or confirm the presence of multiple Higgs particles?

The Large Hadron Collider (LHC) at CERN is currently the only experimental facility capable of producing and detecting Higgs particles. By studying the properties and interactions of the Higgs boson, scientists can gather evidence for the existence of multiple Higgs particles.

5. What are the implications of multiple Higgs particles for the future of particle physics?

If multiple Higgs particles are discovered, it would open up new avenues for research and potentially lead to the development of new theories beyond the Standard Model. It could also provide a better understanding of the fundamental forces and particles in the universe.
