SUMMARY

The discussion centers on the detection of superparticles, specifically neutralinos, at the Large Hadron Collider (LHC). Neutralinos, classified as Weakly Interacting Massive Particles (WIMPs), are challenging to detect due to their lack of electric charge, rendering them non-reactive to electromagnetic detection methods. The conversation also touches on the potential detection of charged superparticles, such as selectrons, which could interact with light and be observable. The concept of supersymmetry is highlighted, indicating that the lightest supersymmetric particle (LSP) is stable and electrically neutral, contributing to the missing energy and momentum signature in experiments.

PREREQUISITES
  • Understanding of supersymmetry and its implications in particle physics
  • Familiarity with Weakly Interacting Massive Particles (WIMPs)
  • Knowledge of the Large Hadron Collider (LHC) and its detection capabilities
  • Basic concepts of particle interactions and electromagnetic detection methods
NEXT STEPS
  • Research the properties and detection methods for selectrons and other charged superparticles
  • Explore the implications of R-parity conservation in supersymmetry
  • Study the role of missing energy and momentum in particle physics experiments
  • Investigate current experimental results from the LHC regarding neutralinos and other superparticles
USEFUL FOR

Particle physicists, researchers in theoretical physics, and anyone interested in the implications of supersymmetry and dark matter detection at the LHC.

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
