在Batalin-Vilkovisky（BV）框架下，详细讨论了修正的三次开超弦场论中Ramond和Neveu-Schwarz（NS）扇区的规范固定问题.我们首次证明了与放松弦场鬼数约束的经典规范不变作用量相同的作用量形式，给出了满足BV主方程的主作用量。这是通过分析逆图像变换算子的核结构来识别独立分量场来实现的。讨论了分量场的明确规范固定条件。在一种b 0 = 0规范中，我们得到了一个NS传播子，它在Virasoro算子L0的零点处有极点。
The gauge-fixing problem in the modified cubic open superstring field theory is discussed in detail for both the Ramond and Neveu-Schwarz (NS) sectors in the Batalin-Vilkovisky (BV) framework. We prove for the first time that the same form of action as the classical gauge-invariant one with the ghost-number constraint on the string field relaxed, gives the master action satisfying the BV master equation. This is achieved by identifying independent component fields by analyzing the kernel structure of the inverse picture-changing operator. The explicit gauge-fixing conditions for the component fields are discussed. In a kind ofb0= 0 gauge, we explicitly obtain an NS propagator that has poles at zeros of the Virasoro operatorL0.
