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.

本研究研究超对称理论，这是一个理论，涉及一个对称性相关的玻色子，粒子的力场在自然界中，费米子，粒子遵守泡利不相容原理，并负责稳定的物质。在自然界中，超对称性不可能是精确的，因为我们没有观察到相同质量的玻色子和费米子对。这项研究将研究超对称性被打破并不再是精确对称的机制。通过研究超对称破缺的影响，我们希望更多地了解超对称理论的高能行为，这会影响超对称如何在低能下破缺，从而影响这些理论与自然的关系。
