来自六维R+R^2 Action的大质量三维超引力

Massive Three-Dimensional Supergravity From R+R^2 Action in Six Dimensions

H. Lu, C. N. Pope, E. Sezgin

摘要:

通过对一个包含曲率平方不变量的离壳N=(1,0)6维庞加莱超引力的3球约化,得到了一个3参数的3维N=1大质量超引力族.三维理论包含一个离壳超引力多重态和一个在壳标量物质多重态。然后,我们概括这在三维的一个八参数家庭的超引力。我们还发现了六维理论和N=(1,0)六维理论之间的对偶关系,这是通过杂化弦有效作用量的T^4约化得到的,其中包含了与反常抵消\tr(R \wedge R)项的超对称化有关的高阶项。

英文摘要:

We obtain a three-parameter family of massive N=1 supergravities in three dimensions from the 3-sphere reduction of an off-shell N=(1,0) six-dimensional Poincare supergravity that includes a curvature squared invariant. The three-dimensional theory contains an off-shell supergravity multiplet and an on-shell scalar matter multiplet. We then generalise this in three dimensions to an eight-parameter family of supergravities. We also find a duality relationship between the six-dimensional theory and the N=(1,0) six-dimensional theory obtained through a T^4 reduction of the heterotic string effective action that includes the higher-order terms associated with the supersymmetrisation of the anomaly-cancelling \tr(R\wedge R) term.
