$θ$ -扭量与超扭量
The $θ$-twistor versus the supertwistor
摘要：
我们引入了$θ$ -扭量，它是Penrose扭量的一个新的超对称推广，也是超扭量的一种替代. $θ$ -扭量是{ \it旋量}的三元组，包括扩展Penrose旋量的双旋量的旋量$θ$。使用$θ$ -扭转子产生无限长的无质量高自旋手征超多重态链$({1/2},1), (1, {3/2}), ({3/2},2),...,(S, S+{1/2})$，推广了已知的标量$(0,{1/2})$超多重态
英文摘要：
We introduce the $θ$-twistor which is a new supersymmetric generalization of the Penrose twistor and is also alternative to the supertwistor. The $θ$-twistor is a triple of {\it spinors} including the spinor $θ$ extending the Penrose's double of spinors. Using the $θ$-twistors yields an infinite chain of massless higher spin chiral supermultiplets $({1/2},1), (1, {3/2}), ({3/2},2),...,(S, S+{1/2})$ generalizing the known scalar $(0,{1/2})$ supermultiplet
