If LHC does not see SUSY-partners, would these falsify SUSY as an explanation for hie

In summary, if the Large Hadron Collider (LHC) does not detect any SUSY-partners, it would not necessarily disprove all SUSY theories. However, it could mean that there is another explanation for the hierarchy problem and that gauge coupling unification may not be enforced by SUSY. The lack of a light Higgs at Fermilab also places constraints on finding SUSY-partners at the LHC. As for the possibility of evidence for higher dimensions at the LHC according to string theory, there is currently no way to assign a probability to this due to the large gap between the LHC's probing capabilities and the Planck scale. Any discoveries or null results at the LHC would have significant implications for the field

If LHC does not see SUSY-partners, of course, this null result would not falsify all SUSY theories, as some SUSY theories could still be realized in nature at a breaking scale some point above 1 TEV, but would a null result falsify SUSY theories that serve as an explanation for hierarchy of the Higgs against quadratic radiative corrections, and falsify the idea SUSY serves to enforce Gauge Coupling Unification?

In otherwords, if SUSY-partners are not found within LHC energies, would these mean there must be some other explanation for the hierarchy problem, and possibly that there is no gauge coupling unification?

How much bounds does not finding a light higgs at Fermilab place on finding SUSY-partners at LHC?

Also how likely will there be evidence of higher dimensions at LHC, according to string theory?

These are good question, which I also would like to know the answer to.
I know string theory only on a popular level but I will risk an answer to the last question:
String theory with its 10^500 vacua does, at the current stage, not seriously allow to assign any probability to large extra dimensions. There is just such a huge gap between the distance scale the LHC can probe and the Planck scale.
Anything can happen.

If there is a null result there is nothing to work with. All we get is a year of "parameter adjustments" to make everything fit like a glove again, in other words further meaningless mathematical manipulation of vapor.

Now if something is found then it would be interesting. :smile:

1. What is SUSY and why is it important in science?

SUSY (Supersymmetry) is a theoretical framework in particle physics that proposes the existence of a new set of particles, known as supersymmetric partners, for every known particle in the Standard Model. It is important because it could potentially solve some of the problems and inconsistencies in the Standard Model, such as the hierarchy problem and the unification of forces.

2. What is the Large Hadron Collider (LHC) and what is its role in the search for SUSY?

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator, located at CERN in Switzerland. Its main purpose is to collide particles at high energies and study the resulting fragments to gain a better understanding of the fundamental building blocks of matter. The LHC is also used to search for new particles, including the predicted supersymmetric partners.

3. If LHC does not find evidence of SUSY-partners, does that mean SUSY is false?

No, it does not necessarily mean that SUSY is false. While the non-observation of supersymmetric particles at the LHC would be a significant setback for the theory, it does not completely falsify it. There are still other ways to test SUSY, such as through indirect effects or other experiments.

4. How would the non-existence of SUSY-partners impact our understanding of the universe?

The non-existence of SUSY-partners would have a significant impact on our understanding of the universe. It would mean that the fundamental principles of SUSY, such as the unification of forces and the stability of the Higgs boson, would need to be reevaluated. It could also lead to the need for new theories to solve the problems that SUSY was proposed to address.

5. What other implications could the non-observation of SUSY-partners have?

The non-observation of SUSY-partners could have implications for other theories beyond the Standard Model, such as string theory. It could also lead to a reevaluation of the hierarchy problem and the search for a theory of everything. Additionally, it could have an impact on the direction of future research in particle physics and the development of new experimental techniques.
