受激超对称破缺

Stimulated Supersymmetry Breaking

Matthew McCullough

摘要:

我们表明,小的软条款可以创建一个超对称破缺最小值沿伪平坦方向的隐藏部门,否则将无法自发的超对称破缺。由于这个最小值沿着伪平坦方向,具有非零的F或D项,因此在隐藏扇区中产生的超对称性破缺可以比创建最小值的软项大几个数量级。这为建立规范中介模型开辟了新的途径,可能对隐藏扇区的宇宙学产生影响,并加强了多个超对称破缺扇区的情况。

英文摘要:

We show that small soft terms can create a supersymmetry breaking minimum along a pseudo-flat direction of a hidden sector which would otherwise be incapable of spontaneous supersymmetry breaking. As this minimum lies along a pseudo-flat direction, with non-zero F- or D-terms, the resultant supersymmetry breaking in the hidden sector can be orders of magnitude greater than the soft terms which created the minimum. This opens new avenues for building models of gauge mediation, may have consequences for the cosmology of hidden sectors, and strengthens the case for multiple supersymmetry breaking sectors.
