Understand

In the minimal supersymmetric standard model, large left-right mixing of stau's is sometimes intriguing from phenomenological viewpoints.

However, too large left-right mixing is not acceptable since the electroweak-breaking vacuum becomes metastable.
In this paper the vacuum transition rate is evaluated by using semiclassical techniques, and constraints on parameters of the model are shown.
In the calculation the bounce solution is derived in the multifield space.
