Title: 六维R+R^2作用下的大尺度三维超引力

Abstract: 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.

Abstract: 我们从一个非定域的N=(1,0)六维Poincare超引力的三维球面约化中得到了一个具有三个参数的三维质量超引力N=1族，该超引力包含曲率平方不变量。 三维理论包含一个非定域超引力多重态和一个定域标量物质多重态。 然后我们将此推广到三维中的八个参数超引力族。 我们也发现了一个六维理论与通过异弦有效作用的T^4约化得到的N=(1,0)六维理论之间的对偶关系，后者包含了与异常抵消项\tr (R\wedge R)的超对称化相关的高阶项。
