Detecting Neutral Super-Partner Particles

[indigojoker]

If SUSY particles existed, is it possible for detectors to pick up on neutral super-partner particles? or would they pass the detector like neutrinos?

 

[mathman]

All neutral particles are harder to detect than charged particles. There is no general rule - each particle is detectable by its specific collision possibilities.

 

[kharranger]

If they are stable, they would not be detectable and would appear as missing energy in a collision. If not, they would decay into other particles which could be detectable.

There is a related concept: WIMP, a Weakly Interacting Massive Particle. Not sure if it is the same than the stable, not decaying, superparticle. Candidates for dark matter.

 

[Nariad]

Indeed, the lightest neutral super-symmetric particles particles would appear as large missing transverse energy in the case where they are stable (when R parity is conserved).

We do not expect to detect the particle but its disintegration products and/or the cross-sectiond of the colision process.

 

[Nariad]

Indeed, we can detected experimentally the charged decay products and reconstruct an invariant mass for different decay products, for many experiments and if in many cases we obtain more or less the same value, we could guess there is a particle with a distribution of invariant mass that is decaying into the daughter particles that we detect.
