In summary, the hierarchy problem in physics refers to the large difference between the weak and gravitational forces, and the question of why the weak force is so much stronger. Scientists have proposed various theories to solve this problem, including supersymmetry, extra dimensions, and the Higgs mechanism. The new model, called the "little hierarchy problem," suggests a new particle, the "little Higgs," can cancel out the large quantum corrections to the Higgs mass. While there is currently no direct evidence for this model, it is consistent with existing data and could have significant implications for our understanding of the fundamental forces and particles of the universe.

Dvali is pretty famous for these far out phenomenology ideas. I remember hearing someone talking about this and thinking, ``Man, what a hell of a thing to look for in a detector.''

Yea, hehe. If the LHC outputs a complete mess, the odds that he ninjas a Nobel prize increases quite dramatically =)
 

1. What is the hierarchy problem in physics?

The hierarchy problem, also known as the hierarchy puzzle, is a theoretical physics problem related to the large disparity between the weak and gravitational forces. The question arises as to why the weak force is so much stronger than gravity, even though gravity is a fundamental force of nature. This leads to the question of whether there is a fundamental underlying reason for this difference or if it is simply a coincidence.

2. How have scientists attempted to solve the hierarchy problem?

Scientists have proposed various theories and models to explain the hierarchy problem, such as supersymmetry, extra dimensions, and the Higgs mechanism. These theories aim to provide a mechanism for why the weak force is so much stronger than gravity, and to explain the hierarchy of particles and their masses.

3. What is the new model on the hierarchy problem?

The new model on the hierarchy problem is called the "little hierarchy problem," which is an extension of the standard model of particle physics. This model proposes that there is a new particle, called the "little Higgs," which helps to cancel out the large quantum corrections to the Higgs mass, thus solving the hierarchy problem.

4. What evidence supports the new model on the hierarchy problem?

There is currently no direct experimental evidence for the little hierarchy problem model. However, it is consistent with existing experimental data and offers a potential solution to the hierarchy problem. Further research and experiments will be needed to test and confirm the validity of this model.

5. What are the potential implications of solving the hierarchy problem?

If the hierarchy problem is solved, it could lead to a better understanding of the fundamental forces and particles of the universe. It could also help to bridge the gap between quantum mechanics and general relativity, two of the most successful theories in physics. Additionally, solving the hierarchy problem could have technological applications, such as developing new energy sources or improving our understanding of the early universe.
