论文摘要
进一步探索了最近引入的无异常扭曲器弦。检查了基于物理状态及其Minkowski解释的频谱。计算涉及重力和费米的顶点算子的散射幅度,并将其与爱因斯坦-yang-mills振幅进行比较。树和一环散射幅度显示具有适当的单一分解特性。最后提出了弦字段理论。
The recently introduced anomaly-free twistor string in 4 dimensions is further explored. The spectrum based on the physical states and its Minkowski interpretation are examined. Scattering amplitudes with vertex operators involving gravitons and fermions are computed and are compared with Einstein-Yang-Mills amplitudes. Tree and one-loop scattering amplitudes are shown to have proper unitary factorization properties. Finally a string field theory is proposed.
