Is MSSM Higgs the Key to Understanding the Universe?

In summary, the conversation is discussing a rumored discovery of a Higgs boson at 160 GeV, which some experts believe is not very plausible. The concept of split supersymmetry is mentioned as a potential explanation for a heavier Higgs, but it is considered junk by many and would create additional problems. The speaker also mentions the possibility of finding a bump in data wherever and whenever desired, and points out that the rumored discovery is only a 2-sigma excess and therefore not significant.

160 GeV ? Mmm. Sounds not so super-symmetric :biggrin:

See comments at Lubos Motl's blog for more on this story.
I'm far from an expert, but here's my take:
Bumps like this two sigma thing come and go all the time and mean nothing.
Most of the experts seem to expect a light Higgs,
but a heavy Higgs, eg near 175 Gev,
is predicted by split supersymmetry,
if I understand the experts correctly.

Split supersymmetry is junk and everyone knows it. It basically abandons any hope of solving the hierarchy problem or naturallness problems and goes with other aesthetic criteria. It explains nothing, and you can move the Higgs mass around a lot.

If they see a Higgs at 175 GeV, and nothing else, the favored models would still likely be a little less minimal SuSy offspring or something a little more contrived (add more degrees of freedom, crank crank crank). One of the nasty consequences is the little hierarchy problem tends to become much more severe and everyone will scramble for a solution to that.

I think that if theory doesn't tell you where your bump is supposed to be, you should look be able to find it pretty much wherever and whenever you want to. If an experimentalists' charts don't have bumps then they don't have the gain turned up enough.

By the way, did you notice the url chosen? "21-sigma" would be a bit more than a bump.

[edit]It appears that D_0 is reporting a deficit where the other guys are reporting a bump.[/edit]

1. What is the MSSM Higgs model?

The MSSM Higgs model is an extension of the Standard Model of particle physics that includes a new type of Higgs boson. This model is based on the theory of supersymmetry, which proposes that every known particle has a yet-to-be-discovered "super partner" particle.

2. Why is the MSSM Higgs model a hot topic in the scientific community?

The MSSM Higgs model is a hot topic because it offers a potential solution to some of the unanswered questions in particle physics, such as the hierarchy problem and the nature of dark matter. It also has implications for the search for new particles at the Large Hadron Collider.

3. How does the MSSM Higgs model differ from the Standard Model?

The main difference between the MSSM Higgs model and the Standard Model is the inclusion of supersymmetry. This leads to additional particles and interactions, as well as a more complex Higgs sector with multiple Higgs bosons.

4. What evidence supports the existence of the MSSM Higgs boson?

Although the MSSM Higgs boson has not yet been directly observed, there is indirect evidence for its existence from precision measurements of other particle interactions. Additionally, the MSSM Higgs model is able to address some of the limitations of the Standard Model, providing further motivation for its existence.

5. How can the MSSM Higgs model be tested and validated?

The MSSM Higgs model can be tested and validated through experiments at particle accelerators, such as the Large Hadron Collider. Scientists can also use data from these experiments to compare with predictions made by the model and look for any discrepancies. Additionally, future experiments and observations of the universe may provide further evidence for the existence of the MSSM Higgs boson.
