Supersymmetry Purpose: Explanation & Purpose

In summary, Supersymmetry may explain the low mass of the Higgs boson, dark matter, and the suitability of supersymmetric particles as dark matter candidates.

Can someone give me an explanation telling me the actual purpose of supersymmetry and what it’s meant to show or predict or solve?

The Wikipedia article gives an introduction. Which part is unclear?

The link between gravity and the fundamental forces of nature is unclear. How is the link shown?
 
  • #4
Supersymmetry has nothing to do with gravity.

That’s what it says on Wikipedia

No I mean on Wikipedia it said it links gravity with the other fundamental forces of nature

Now it doesn't do that any more. No idea who added that, but apparently no one caught it.

Oh, so are you able to answer my question or?

The Wikipedia article gives a [now better] introduction. Which part is unclear?

That will teach you to rely solely on Wikipedia.

Why don't you look at this instead?

Oh right I like this guy he explains things well ill watch it thanks !

Supersymmetry was invented to explain:
1. Relatively low mass of Higgs boson.
Without approximately electroweak scale supersymmetry it seems that mass of Higgs is somehow fine tuned, eg designed, what implies improbable serendipity, divine intervention or an anthropic principle at work - scientists hate all of these ideas but it seems that they will have to reconsider them and pick their poison.
2. Supersymmetric particles are nice candidates for dark matter.
3. Without supersymmetry string theories and particularly their applications in ultrahigh energy physics are ruined and a lot of work in theoretical physics is good for nothing.

Martin0001, none of what you wrote is correct.

  1. Supersymmetry was invented in the late 1960's and early 1970's, long before the Higgs boson's mass was known, or even bounded.
  2. A consensus that DM must have a particle (specifically, non-baryonic) nature did not develop until the 1980's.
  3. That just sounds bitter.

You are right, but current work and support of supersymmetry is related to issues which I have risen. There was (and still is albeit it fades) a hope that supersymmetry will resolve these issues.
And yes, point 3, even if bitter, still holds - string theories applicable in ultrahigh energy physics need supersymmetry to work.

Sometimes people say that susy is linked to gravity because a local supersymmetry is able to predict gravity -eg gravitinos- (local supersymmetry = supergravity)...
 

1. What is supersymmetry?

Supersymmetry is a theoretical framework in physics that proposes the existence of a new type of symmetry between fundamental particles. It suggests that for every known elementary particle, there exists a corresponding "superpartner" particle with a different spin.

2. What is the purpose of studying supersymmetry?

The main purpose of studying supersymmetry is to address some of the limitations of the Standard Model of particle physics. Supersymmetry provides a potential solution to the hierarchy problem, which is the large disparity between the energy scales of gravity and the other fundamental forces. It also offers a way to incorporate gravity into the Standard Model and provides a possible candidate for dark matter.

3. How does supersymmetry relate to string theory?

Supersymmetry is a key component of string theory, a theoretical framework that attempts to unify all of the fundamental forces of nature. In string theory, the existence of supersymmetry is necessary for the consistency of the theory and helps to solve certain mathematical problems that arise.

4. Is there any experimental evidence for supersymmetry?

At this time, there is no direct experimental evidence for supersymmetry. However, many physicists believe that it is a promising avenue for further research and are actively searching for evidence through experiments at high-energy particle accelerators like the Large Hadron Collider.

5. What are the potential implications of discovering supersymmetry?

If supersymmetry is discovered, it would revolutionize our understanding of the fundamental building blocks of the universe. It could also have practical applications, such as helping to explain the nature of dark matter and potentially leading to new technologies. Additionally, the discovery of supersymmetry would provide a major breakthrough in our quest for a more complete and unified theory of physics.
