Among the solutions of string theory and supergravity which preserve some fraction of supersymmetry, the best known are those that leave one half of the supersymmetry unbroken, and there is a large number of field theory models with this pattern of supersymmetry breaking. However, a lot of brane configurations exist which preserve only $1/4$, $1/8$ or more exotic fractions of supersymmetry, and field theory side of these systems remains largely unexplored. To find whether the formalism of nonlinear realizations is useful in construction of models of this type, we consider the systems of some $N_0$ scalar and vector $N=1$, $d=3$ Goldstone supermultiplets. We find that it is possible to construct an $SO(N_0)$ invariant theory of $N_0$ scalar multiplets with $N_0$ broken supersymmetries. For $N_0=3$ or $N_0\geq 5$ its action is not of Nambu-Goto type and its structure remains universal for arbitrary $N_0$. The cases of $N_0=1,2$ correspond to the membranes in $D=4$ and $D=5$, respectively, while for $N_0=4$ some arbitrariness in the action remains, and with proper choice of parameters, it is possible to obtain the action of the membrane in $D=7$ in the bosonic limit. It is also shown that the $SO(N_0)$ invariant action of $N_0$ vector multiplets with $1/N_0$ pattern of supersymmetry breaking does not exist for arbitrary $N_0$.

任意数量d=3超对称性的部分破缺

在保留部分超对称性的弦论和超引力的解决方案中,最著名的是保留一半超对称性的解决方案,并且存在大量具有这种超对称性破缺模式的场论模型。然而,存在许多仅保留 $1/4$、$1/8$ 或更多超对称性的奇异分数的膜配置,并且这些系统的场论方面在很大程度上仍未得到探索。为了找出非线性实现的形式主义在构建这种类型的模型中是否有用,我们考虑一些 $N_0$ 标量和向量 $N=1$、$d=3$ Goldstone 超多重子的系统。我们发现可以构建一个 $N_0$ 标量多重态的 $SO(N_0)$ 不变理论,其中 $N_0$ 破坏了超对称性。对于 $N_0=3$ 或 $N_0\geq 5$,它的动作不是 Nambu-Goto 类型的,它的结构对于任意的 $N_0$ 仍然是通用的。$ n_0 = 1,2 $的情况分别对应于$ d = 4 $和$ d = 5 $的膜,而在剩下的$ n_0 = 4 $ 4 $ 4 $ 4 $ 4 $ 4 $ 4 $。有可能在玻色子极限的 $D=7$ 中获得膜的作用。还表明,对于任意的 $N_0$,具有 $1/N_0$ 超对称破缺模式的 $N_0$ 向量多重态的 $SO(N_0)$ 不变作用不存在。有可能在玻色子极限的 $D=7$ 中获得膜的作用。还表明,对于任意的 $N_0$,具有 $1/N_0$ 超对称破缺模式的 $N_0$ 向量多重态的 $SO(N_0)$ 不变作用不存在。有可能在玻色子极限的 $D=7$ 中获得膜的作用。还表明,对于任意的 $N_0$,具有 $1/N_0$ 超对称破缺模式的 $N_0$ 向量多重态的 $SO(N_0)$ 不变作用不存在。
