Beyond the Standard Model of Particle Physics

tanmay writes "As time moves on, the case for supersymmetry keeps getting stronger. Physicsweb is reporting about an experiment that measures the relation between the spin of the muon and its magnetic moment, called the g-factor. The latest experiment is described as the most significant deviation to date between experiment and theory in particle physics, thus offering the clearest hint so far of new physics beyond the Standard Model of particle physics. We will know for sure if supersymmetry holds it's ground by 2007, when the Large Hadron Collider will commence operation."

This is false. They didn't need the SCSC to make this discovery. They did it at the Brookhaven National Laboratory, which does not have a particularly high energy collider.

All they did was refine some data from the 1970s experiment, which leads to the startling conclusion that the Standard Model is not a perfect description.

Most tee vee shows like Nova assume that the only way to show that the Standard Model is not a perfect description is by using higher and higher energy colliders (like the SCSC).

Where's my squark?

We'll know for sure that supersymmetry holds it's own when we find an selectron. However, I find it odd that we have a standard modle full of particles, but yet have not found any of their sparticles. Is it that sparticles are beyond the range of todays accelerators or is it that they don't exist? The only thing for certain is that it will ensure employment for a few particle physicists.
