Destablization

补记感恩节前的报告
This is a talk given by Jon right before Thanksgiving.
he and Adam Falk’s work is about one soft breaking term(Hall-Randall) that people previously thought may appear in SUSY breaking lagrangian. They study from spontonously breaking, found goldstino loop always appears along with this soft breaking term, just as pion decay term always appears with mass term(Goldberger-Treiman relation). Thus, if you don’t suppress the breaking term by suitable power counting factor(after that it will become small), the goldstino loop will destablize the vacuum.
The work is cool, however it lasted 7 years. In the beginning Jon said: ‘Everyone should thank something in Thanksgiving, I thank this work being finished’.
