摘要:

研究了五元函数Hilbert空间上SO(6,2)的最小酉表示(minrep),通过量子化它的拟共形实现得到. SO(6,2)的最小表示与SO*(8)的最小表示一致,对应于6维时空中的无质量共形标量场。SO*(8)的极小表示存在一族“形变”,用类光矢量的子群SO(4)的SU(2)T子群的自旋t来标记。这些由t标记的变形是SO*(8)的正能量酉不可约表示,描述了六维无质量共形场。SU(2)T自旋t是四维共形群SU(2,2)的minrep的U(1)形变的六维对应,用螺旋度标记.我们还构造了SO ~*(8)的极小酉表示到OSp ~*(8)的极小酉表示的超对称扩张|2N)描述无质量的六维共形超多重态。OSp(8*)的最小酉超多重态|4)是(2,0)共形场论的无质量超多重态,它被认为是AdS_7 x S^4上M理论的对偶。

英文摘要:

We study the minimal unitary representation (minrep) of SO(6,2) over an Hilbert space of functions of five variables, obtained by quantizing its quasiconformal realization. The minrep of SO(6,2), which coincides with the minrep of SO*(8) similarly constructed, corresponds to a massless conformal scalar field in six spacetime dimensions. There exists a family of "deformations" of the minrep of SO*(8) labeled by the spin t of an SU(2)_T subgroup of the little group SO(4) of lightlike vectors. These deformations labeled by t are positive energy unitary irreducible representations of SO*(8) that describe massless conformal fields in six dimensions. The SU(2)_T spin t is the six dimensional counterpart of U(1) deformations of the minrep of 4D conformal group SU(2,2) labeled by helicity. We also construct the supersymmetric extensions of the minimal unitary representation of SO*(8) to minimal unitary representations of OSp(8*|2N) that describe massless six dimensional conformal supermultiplets. The minimal unitary supermultiplet of OSp(8*|4) is the massless supermultiplet of (2,0) conformal field theory that is believed to be dual to M-theory on AdS_7 x S^4.
