超对称U(1)模型中的标量势和偶然对称性

Scalar Potentials and Accidental Symmetries in Supersymmetric U(1)' Models

Paul Langacker, Gil Paz, Itay Yavin

摘要:

我们解决了两个密切相关的问题,与单重标量的潜力,经常出现在超对称U(1)的模型,特别是那些保持规范统一的MSSM在一个简单的方式。第一种可能性是偶然的全局对称性,它导致了轻的戈德斯通玻色子。第二个问题是在不重新引入$μ$问题的情况下为多个场生成真空期望值的问题。我们为解决这两个问题提供了充分的条件,并提供了一个具体的例子来产生它们。

英文摘要:

We address two closely related problems associated with the singlet scalars' potential that are often present in supersymmetric U(1)' models, especially those which maintain the gauge unification of the MSSM in a simple way. The first is the possibility of an accidental global symmetry which results in a light Goldstone boson. The second is the problem of generating a vacuum expectation value for more than one field without reintroducing the $μ$ problem. We give sufficient conditions for addressing both issues and provide a concrete example to generate them.
