Why don't we see super-symmetric particles?

we can se many particles, also we can detect and produce antimatter

however my question is why even at high energies we can not see any supersymmetric partner of a particle ?

Supersymmetry is not an experimentally verified theory. There are two possibilities:

1 The SUSY scale is significantly higher than many would have argued before LHC or otherwise hidden.
2 SUSY does not exist.

Vote early and vote often.

There is also the possibility that the spectrum is such that it is just too hard to see. For example, if you had a stop squark just a little heavier than the top quark and only a moderately heavy LSP, you'd produce a few percent extra events that looked like top-antitiop, possibly with a smidgen more missing energy. Hard to spot and very hard to spot if you aren't specifically looking for it,

I tried to include things like this in 1 with the ”otherwise hidden” to not make it too long … 🤔

While there is a whole cottage industry of people who propose hiding places - an industry of which I am not part - having a stop mass near the top mass has some desirable features. Apart from being difficult to disprove. It's not just hard to find.

There is a paper in preparation by one of the LHC experiments that may soon shed some light on this region. Maybe in a month or two it will be in print.

1. Why haven't super-symmetric particles been discovered yet?

Super-symmetric particles have not been discovered yet because they are predicted to be much heavier than the particles we have already discovered. This means that they would require higher energies to produce, which have not yet been achieved in experiments.

2. Are super-symmetric particles ruled out by current experiments?

No, super-symmetric particles are not ruled out by current experiments. While no direct evidence of super-symmetry has been found, the theory is still considered a viable possibility to explain some of the mysteries in particle physics.

3. What are the implications if super-symmetric particles are never discovered?

If super-symmetric particles are never discovered, it would mean that the theory of super-symmetry is incorrect or incomplete. This would lead to a reevaluation of our understanding of fundamental particles and forces in the universe.

4. Could super-symmetric particles be hiding in plain sight?

It is possible that super-symmetric particles could be hiding in plain sight, but are simply too difficult to detect with current experimental methods. Scientists continue to search for new ways to probe for these elusive particles.

5. How would the discovery of super-symmetric particles impact our understanding of the universe?

The discovery of super-symmetric particles would have profound implications for our understanding of the universe. It could help explain the existence of dark matter, unify the forces of nature, and provide new insights into the fundamental structure of the universe.
