在IIB型光锥超弦场论中，立方相互作用有两部分：δ函数重叠和在相互作用点插入的算符。本文推广了我们以前的工作，在pp-波弦理论的振子基中，对所有μp+ π '，计算了这个算子的矩阵元。通过对大μp+α'的矩阵元的计算，我们检验了最近关于光锥弦场论哈密顿量（带前因子）的矩阵元与规范理论中BMN算符的某些三点函数的关系的一个猜想。我们还对规范理论作了几个预言。
In type-IIB light-cone superstring field theory, the cubic interaction has two pieces: a delta-functional overlap and an operator inserted at the interaction point. In this paper we extend our earlier work by computing the matrix elements of this operator in the oscillator basis of pp-wave string theory for all μp+α'. By evaluating these matrix elements for large μp+α' , we check a recent conjecture relating matrix elements of the light-cone string field theory hamiltonian (with prefactor) to certain three-point functions of BMN operators in the gauge theory. We also make several predictions for gauge theory.
