Can Superparticles with Charge be Detected at the LHC?

In summary, the LHC may potentially discover neutralinos, which are a type of WIMP that are difficult to detect due to their lack of charge. However, it is possible that other superparticles with charge, such as the selectron or super particle of a proton, could be detected through their interactions with light. Supersymmetry is often postulated to be conserved, meaning that the lightest supersymmetric particle, the neutralino, could potentially be seen as missing energy and momentum in experiments.

The LHC may help discover the existence of neutralinos, which are WIMPs and hard to detect.

If this is due their charge being 0 and therefore non-reactive to EM detection, why can't we detect another superparticle,one that does have a charge, and therefore reacts with light so that we could detect it?
eg the selectron or the super particle of a proton?

thanks

I usually leave the replies to people who know what they are talking about. Unfortunately none of them have chimed in.

It is usually thought that supersymmetry is a badly broken symmetry. Which is a fancy way of saying superparticles are heavy, maybe a TeV, which is why they haven't been seen.

It is often postulated that supersymmetry is conserved. (They call it R-gauge or some fancy term like that.) So the lightest supersymetric particle (LSP) is stable and should be buzzing around the universe if it exists. The LSP is electrically neutral and colorless from cosmology constraints so the neutralino is an excellent candidate for it.

the lightest, stable superparticle will not interact with ordinary matter (including the detector); therefore the signature is missing energy and momentum
 

Related to Can Superparticles with Charge be Detected at the LHC?

1. What are superparticles?

Superparticles are hypothetical particles that are predicted by theories beyond the Standard Model of particle physics. They are thought to have properties such as mass, spin, and charge that differ from those of known particles.

2. How are superparticles detected?

Superparticles are detected indirectly through their decay products. These decay products can be detected using specialized detectors in particle colliders, such as the Large Hadron Collider, or through observations of cosmic rays.

3. What is the significance of detecting superparticles?

Detecting superparticles would provide evidence for the existence of new physics beyond the Standard Model. This would greatly advance our understanding of the fundamental building blocks of the universe and could potentially lead to new technologies.

4. Are there any current experiments or research focused on detecting superparticles?

Yes, scientists at various research institutions and particle colliders around the world are conducting experiments and research to search for evidence of superparticles. These include the Large Hadron Collider at CERN and the Super-Kamiokande experiment in Japan.

5. What challenges are involved in detecting superparticles?

One of the main challenges in detecting superparticles is that they are predicted to have very high energies and short lifetimes, making them difficult to detect and observe. Additionally, there are many different theories and models that predict the existence of superparticles, making it challenging to know where to look for them.
