SUSY

Buchmueller is looking to see proof of super-symmetry -- dubbed SUSY -- which allows for the existence of unseen doubles of basic particles which could explain the existence of the dark matter believed to make up one quarter of the known universe.

This kind of SUSY is not yet completely ruled out (it might be at the LHC), but we know that it is not natural - this is expressed by the buzzwords “SUSY requires fine-tuning at the percent level”.

I have expressed some interest in High Energy Physics and various QC, GUT and SUSY theories on occasion.

This depends upon what the SUSY partner of the Higgs field is.

If we can detect N = 4 SUSY quaternionic or 16 supersymmetries in the Clifford algebra CL_16, most likely in a broken symmetry phase, we would be in great shape!

Abstract: I review recent developments on the use of mT2 variables for SUSY parameter study, which might be useful for the data analysis in the early stage of the LHC experiments.

What would it take to have confidence that electroweak baryogenesis within a particular SUSY model actually occurred?

On the other hand, SUSY can help explain why the Higgs scale is so much lower than the Planck scale — the hierarchy problem — if and only if it is broken at a low enough scale to be detectable at the LHC.

If anything, the history of particle physics teaches us that surprises abound: often, whenever a natural hypothesis prevailed (relatively heavy SUSY WIMPs or light axions in our case) incoming experimental data forced the community to regroup, rethink and come up with other explanations.
