B Supersymmetry Purpose: Explanation & Purpose

[Vishal Rana]

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

 

[mfb]

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

 

[Vishal Rana]

The link between gravity and the fundamental forces of nature is unclear. How is the link shown?

 

[mfb]

Supersymmetry has nothing to do with gravity.

Supersymmetry has nothing to do with gravity.

That’s what it says on Wikipedia

 

[mfb]

So what is unclear?

 

[Vishal Rana]

So what is unclear?

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

 

[mfb]

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?



Zz.

I’ll take a look thanks

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)...
