is super symmetry real or has been predicted by string theory?
Is Super Symmetry Real: String Theory Predictions

In summary: Supersymmetry is a consequence of string theory, in the sense that it arises as a natural consequence of the theory's basic symmetry principles.

- There is no experimental evidence for supersymmetry, yet. A lot of people set hope into the Large Hadron Collider at CERN (european center for nuclear and particle physics) to find superpartners of known particles and hence (more or less) prove susy to exist.
- It's not a prediction by string theory but a necessary component of some string models (hence the name superstrings)*. It's not something unique to string theory, though. You can apply supersymmetry more or less directly to the SM which in the minimal version of a realistic model leads to the minimal supersymmetric standard model (MSSM), which might well be the most-examined model for physics beyond the standard model.
*: I'm not a stringer. It might be that it's a fundamental building block for all string models as some SUSY guy told me. However, since some stringer told us in a talk that there's string models with susy and string models without, I'm more inclined to believe that version, even though that information is a bit older.

All true, but it is still worth saying that it is really only in string theory that supersymmetry arises naturally.

Taking the maximum extension of spacetime symmetries already appears relatively natural (
) to me. How does it "arise naturally" in string theory (also in the sense of "what does that mean?") and what does that mean about string models without susy? If susy automatically arises from a string approach, then it seems that non-susy string models shouldn't be possible.

Hello,
Yes, I would be glad to know how does susy appear in string theory ? Is it a consequence of strings or extra-dimensions (which can be wo strings) or both or something else ?
Thanks.

FAQ: Is Super Symmetry Real: String Theory Predictions
1. What is Super Symmetry and how does it relate to String Theory?
Super Symmetry is a theoretical concept in physics that proposes a new symmetry between particles. It suggests that every particle has a partner particle with similar properties, but with opposite spin. This concept is related to String Theory because it is a key component in many string theory models, providing a possible solution to some of the theory's mathematical inconsistencies.
2. Is there any evidence for Super Symmetry in the real world?
As of now, there is no direct experimental evidence for Super Symmetry in the real world. Many experiments, including the Large Hadron Collider, have been conducted to search for evidence of Super Symmetry, but it has not been observed yet. However, some indirect evidence and theoretical predictions support the possibility of its existence.
3. Can Super Symmetry be tested or proven?
Super Symmetry is a theoretical concept, so it cannot be directly tested or proven. However, scientists can test predictions and implications of Super Symmetry through experiments and observations. If these predictions are confirmed, it could provide strong evidence for the existence of Super Symmetry.
4. Are there any drawbacks or criticisms of Super Symmetry?
One of the main criticisms of Super Symmetry is that it has not been observed in any experiments, despite many years of research and numerous attempts to detect it. This lack of evidence has led some scientists to question the validity of the theory. Additionally, Super Symmetry requires the existence of new, undiscovered particles, which some find to be too speculative.
5. How does the existence of Super Symmetry impact our understanding of the universe?
If Super Symmetry is proven to be real, it would have a significant impact on our understanding of the universe. It would provide a more complete understanding of the fundamental particles and forces that make up the universe and could potentially help to bridge the gap between quantum mechanics and general relativity. Additionally, it could help to explain some of the mysteries of the universe, such as dark matter.
