共振超代数与三维时空中的$\mathcal{N}=1$超引力理论

Resonant superalgebras and $\mathcal{N}=1$ supergravity theories in three spacetime dimensions

Patrick Concha, Remigiusz Durka, Evelyn Rodríguez

摘要:

我们探讨$\mathcal{N}=1$超对称扩展代数超越庞加莱和AdS的三维时空。除了再现两个已知的例子,我们提出了新的超代数,这都对应于超对称扩展与一个费米子电荷$Q_α$关于所谓的共振代数的特点是存在一个额外的玻色子生成器$Z_{a}$,除了洛伦兹$J_{a}$和平移$P_{a}$生成器。得到了8个超对称$JPZ+Q$格式,它们是由服从超Jacobi恒等式直接得到的.我们指出了特殊的要求,超代数必须满足成功地纳入有效的超引力行动。所提出的代数和拉格朗日框架组织,并帮助我们更好地理解各种超引力和超对称陈-西蒙斯行动之间的关系在不同的共振超代数不变。

英文摘要:

We explore $\mathcal{N}=1$ supersymmetric extensions of algebras going beyond the Poincaré and AdS ones in three spacetime dimensions. Besides reproducing two known examples, we present new superalgebras, which all correspond to supersymmetric extensions with one fermionic charge $Q_α$ concerning the so-called resonant algebras being characterized by the presence of an additional bosonic generator $Z_{a}$, besides the Lorentz $J_{a}$ and translation $P_{a}$ generators. Obtained eight supersymmetric $JPZ+Q$ schemes result directly from obeying super-Jacobi identities. We point out particular requirements that superalgebras have to satisfy to be successfully incorporated within valid supergravity actions. The presented algebraic and Lagrangian framework organizes and helps us better understand relations between the various supergravity and supersymmetric Chern-Simons actions invariant under diverse resonant superalgebras.
