Lattice QCD calculations of the hadronic corrections to the anamalous magnetic moment of the muon.

There has been a long standing tension between the experimentally measured anamalous magnetic moment of the muon and the theoretical prediction from the standard model of particle physics. It could be that the reason for this deviation between experiment and theory means that some new novel particles need to be added to the standard model of particle physics and thus a deeper new theoretical is developed. However, there is some uncertainity in the contribution of the hadronic corrections to the theoretical calculation and unless these calculations are done reliably then we will never know whether new particles are required. One way to compute the required hadronic corrections is to use a technique called lattice QCD on large supercomputers, such as those owned by DiRAC. The project will involve computing isospsin broken contributions to the hadronic contributions to the anamalous magnetic moment of the muon using large scale computers.

The Muon g-2 ring sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the precession (or wobble) of muons as they travel through the magnetic field.
