大规模3D超重力

Massive 3D Supergravity

Roel Andringa, Eric A. Bergshoeff, Mees de Roo, Olaf Hohm, Ergin Sezgin, Paul K. Townsend

摘要:

我们构造了N=1的三维超引力理论与宇宙,Einstein-Hilbert,Lorentz Chern-Simons,和一般曲率平方项。我们确定了一般的超对称位形,并以超对称Minkowski真空为极限情形,找到了一族超对称adS真空。线性化的闵可夫斯基真空,我们发现三类酉理论,一个是最近发现的“大质量三维引力”的超对称扩展。另一个是“新的拓扑大质量超引力”(没有爱因斯坦-希尔伯特项),传播一个单一的(2,3/2)螺旋度超多重态。

英文摘要:

We construct the N=1 three-dimensional supergravity theory with cosmological, Einstein-Hilbert, Lorentz Chern-Simons, and general curvature squared terms. We determine the general supersymmetric configuration, and find a family of supersymmetric adS vacua with the supersymmetric Minkowski vacuum as a limiting case. Linearizing about the Minkowski vacuum, we find three classes of unitary theories; one is the supersymmetric extension of the recently discovered `massive 3D gravity'. Another is a `new topologically massive supergravity' (with no Einstein-Hilbert term) that propagates a single (2,3/2) helicity supermultiplet.
