关于无鬼超对称伽利略子

On Ghost-free Supersymmetric Galileons

Fotis Farakos, Cristiano Germani, Alex Kehagias

摘要:

我们提出了一致的超对称理论不变的推广下的伽利略移位对称${\cal{N}}=1$超空间。这些理论是通过某些非最小导数耦合超引力的解耦极限构建的,因此它们对应于所谓的协变Galileon的超对称化。具体地说,这些理论被构造在线性化的${\cal{N}}=1$新的最小超引力设置,手征超多重态是最小耦合到重力通过标准的R-电流接触项,并在同一时间,非最小导数耦合到爱因斯坦超场。

英文摘要:

We present consistent supersymmetric theories invariant under the generalization of the Galilean shift symmetry to ${\cal{N}}=1$ superspace. These theories are constructed via the decoupling limit of certain non-minimally derivative coupled supergravities, thus they correspond to the supersymmetrization of the so-called covariant Galileon. Specifically, these theories are constructed in the linearized ${\cal{N}}=1$ new-minimal supergravity set-up where the chiral supermultiplet is minimally coupled to gravity via the standard R-current contact term, and, at the same time, non-minimally derivatively coupled to the Einstein superfield.
