What are the implications of supersymmetry for the Higgs boson and its mass?

In summary, supersymmetry is a theoretical framework that proposes a symmetry between fermions and bosons in particle physics, while the Higgs field is a fundamental field that gives mass to particles. Supersymmetry suggests that for every boson in the Standard Model, there exists a fermionic partner, including the Higgsino. The search for supersymmetry and the Higgs is important because it could help explain phenomena in particle physics and provide evidence for new particles and interactions. While there have been supporting experiments and observations, the theory has not been conclusively proven and further research is needed.

Hello all,

How is it that super symmetry accounts for the Higgs having a mass and what would the 4 remaining Higgs bosons account for?

You don't need SUSY to account for the Higgs boson having a mass. The Standard Model does that just fine (the Higgs boson gets its mass by interacting with the Higgs field (roughly speaking) much the same as all the other particles with mass). SUSY can help explain why the mass is around the electroweak scale though. As for how, well it is a little technical and we'd have to start talking about the hierarchy problem.

As for what the extra SUSY Higgses "account for", well, nothing. They are just needed if you want SUSY to solve the aforementioned hierarchy problem.

In the minimal supersymmetric Standard Model (MSSM), there is a conjectured potential for the Higgs fields that leads to a mass via a slightly more complicated version of the usual Higgs mechanism. The extra Higgs bosons are just extra scalar particles (that haven't been detected, of course), which include both neutral and electrically charged particles. The masses of these particles are parameter dependent.

Many details are discussed in http://arxiv.org/abs/hepph/9709356, but you would need a good QFT background to understand it completely.

What is supersymmetry?

Supersymmetry is a theoretical framework that proposes a symmetry between fermions (particles with half-integer spin) and bosons (particles with integer spin) in particle physics. It suggests that for every known particle, there exists a yet-to-be-discovered "superpartner" particle with a different spin.

What is the Higgs field?

The Higgs field is a fundamental field in particle physics that is theorized to give mass to particles. It is believed to permeate the entire universe, and particles that interact with the Higgs field gain mass while those that do not remain massless.

How does supersymmetry relate to the Higgs field?

Supersymmetry suggests that for every boson in the Standard Model (which describes all known particles and their interactions), there exists a fermionic partner. This would include a superpartner for the Higgs boson, called the Higgsino, which plays a crucial role in the mechanism of electroweak symmetry breaking.

Why is the search for supersymmetry and the Higgs important?

The search for supersymmetry and the Higgs is important because it could help explain certain phenomena in particle physics, such as the hierarchy problem (the large discrepancy between the strength of gravity and the other fundamental forces) and the nature of dark matter. It could also provide evidence for the existence of new particles and interactions beyond the Standard Model.

Has supersymmetry and the Higgs been proven experimentally?

Although the theory of supersymmetry and the Higgs has not been conclusively proven, there have been many experiments and observations that support its existence. The discovery of the Higgs boson at the Large Hadron Collider in 2012 was a major step towards validating this theory, but more data and experiments are needed to confirm its predictions.
