This research studies supersymmetric theories, which are theories that involve a symmetry relating bosons, the particles responsible for force fields in nature, to fermions, the particles which obey the Pauli exclusion principle, and which are responsible for stable matter. In nature supersymmetry cannot be exact as we do not observe pairs of bosons and fermions at the same mass. This research will study the mechanism by which supersymmetry is broken and ceases to be an exact symmetry. By looking at the effects of the supersymmetry breaking we hope to learn more about the high energy behaviour of supersymmetric theories, which affects how the supersymmetry is broken at low energies and thus, how these theories relate to nature.

这项研究研究了超对称理论，这些理论涉及玻色子的对称性，负责力场的粒子与费米子，遵守Pauli排除原理的粒子以及负责稳定物质的粒子。在自然界中，超对称性不能精确，因为我们不观察到同一质量的玻色子和费米子对。这项研究将研究超对称性破裂并停止成为确切对称性的机制。通过查看超对称性破裂的影响，我们希望更多地了解超对称理论的高能量行为，这会影响超对称性在低能量下打破的方式，从而影响这些理论与自然的关系。
