Supersymmetry

Short Description of Topic

The Main Idea

The main idea being discussed is the popular particle physics theory, Supersymmetry. One of the main goals of supersymmetry is to unify Quantum Theory with Einstein's General Relativity(Gravity). It does so by enumerating different types of elementary particles found in our universe to explain happenings in the microverse, by relating two types of elementary particles, Bosons and Fermions. Each particle from one group would have a super partner in the other group which has the a different weight, and the spin being separated by half an integer.

Consequences of Supersymmetry

One of the consequences of Supersymmetry would be that the number of particles that we know now in the standard model would be doubled. This is so that the super particles can counteract their regular particles much like anti-matter does for matter. Supersymmetry can also help to link the strong, weak, and electromagnetic forces together

In the first graph above you can see that in the standard model without supersymmetry at high energies the three forces become close to each other. In the graph to the left of that however you can see that with supersymmetry the three become equal at some high energy point. Another interesting consequence that could come of supersymmetry is the explanation of what dark matter is. Normal matter, the things we can observe in our everyday lives, is approximately 4% of the known universe. Dark matter is thought to take up more than 20% of our known universe, and supersymmetry could help to explain that. Dark matter are weakly interacting particles that are thought to help bind large bodies together despite what would normally be weak gravitational pull between them at the speeds they move, such as galaxies. Galaxies move too quickly for the stars contained within them to stay bound without dark matter.

The graph above shows how fast the velocities within a solar system should be at size without dark matter, and then above all of these graphs is shown how fast they are actually moving.

A Mathematical Model

What are the mathematical equations that allow us to model this topic. For example [math]\displaystyle{ {\frac{d\vec{p}}{dt}}_{system} = \vec{F}_{net} }[/math] where p is the momentum of the system and F is the net force from the surroundings.

History

Hironari Miyazawa was the first person to propose supersymmetry, and his was relating mesons and baryons. Because of how broken his symmetry was, his work was largely ignored. 2 groups of scientists all independently began working on a supersymmetry in quantum field theory around the same time, J. L. Gervais and B. Sakita(1971), Yu. A. Golfand and E. P. Likhtman(1971), and D. V. Volkov and V. P. Akulov(1972). The Gervais-Sakita works arose because of an early version of string theory. The model proposed by Pierre Fayet known as the Minimal Supersymmetric Standard Model was the first realistic model in superstring theory proposed.
