Is SUSY Facing Its Demise? Examining the LHC's Latest Results

In summary, the conversation suggests that the search for supersymmetric particles at the LHC has not been successful and there may be limitations on the mass of these particles. The hope for supersymmetry is that it can help with the fine-tuning needed for the Higgs mass, but there may be other alternative theories that need to be considered. The discussion about the physics of supersymmetry should be done in a separate forum dedicated to beyond the Standard Model theories.

Super Partners have not been seen by LHC

How very hyped up. In all honesty, I think a great many things will have to be altered in the Standard Model before any unification is achieved.

I guess that there are reasons why the masses of the supersymmetric particles cannot be shifted arbitrarily high ?

The hope for super-symmetry is that it can be used to avoid the fine-tuning needed for the Higgs mass. For that, you need soft-breaking near the TeV scale.

Do we have any near alternative theories against SUSY? If not, we could not help using SUSY.
 
  • #5
Discussion about the physics of SUSY should be done in the Beyond The Standard Model forum. This thread is limited only to reporting what the LHC (both CMS and ATLAS) has not discovered per the expected SUSY particles.

FAQ: Is SUSY Facing Its Demise? Examining the LHC's Latest Results

What is SUSY?

SUSY (short for supersymmetry) is a theoretical concept in particle physics that suggests the existence of a new set of particles that would provide a symmetry between fermions and bosons.

Why is there speculation that SUSY may soon be ruled out?

Despite decades of research, there has been no experimental evidence to support the existence of supersymmetric particles. This has led many scientists to question its validity and consider the possibility that it may soon be ruled out.

What experiments have been conducted to test SUSY?

Several experiments, such as the Large Hadron Collider (LHC) at CERN, have been conducted to search for evidence of supersymmetric particles. However, none have been successful so far.

What would ruling out SUSY mean for the field of particle physics?

If SUSY is indeed ruled out, it would mean that the Standard Model of particle physics, which has been the basis of our understanding of the fundamental particles and forces of nature, would need to be revised or replaced with a new theory.

Is there still hope for SUSY to be supported by experimental evidence?

While the lack of evidence has led many to doubt the validity of SUSY, there are still some scientists who believe that it may be supported by future experiments. Only time and further research will tell if SUSY will be ruled out or not.
