标题： Extended string field theory for massless higher-spin fields

摘要： 我们提出一种新的规范场理论，它是通过组合玻色弦的多个状态空间对普通弦场理论的扩展。 该理论在其无质量谱中包含高自旋场以及无限质量场族。 从该理论中，我们可以轻松提取具有任何对称性的张量场的最小规范不变二次作用量。 作为例子，我们显式推导了一些简单混合对称张量场的规范不变作用量。 我们还通过扩展用于弦场理论的方法构建了协变规范固定的行动。 显示英文摘要

摘要： We propose a new gauge field theory which is an extension of ordinary string field theory by assembling multiple state spaces of the bosonic string. The theory includes higher spin fields in its massless spectrum together with the infinite tower of massive fields. From the theory, we can easily extract the minimal gauge invariant quadratic action for tensor fields with any symmetry. As examples, we explicitly derive the gauge invariant actions for some simple mixed symmetric tensor fields. We also construct covariantly gauge-fixed action by extending the method developed for string field theory.
