利用开+闭弦场理论研究了IIB型平面波背景下的开弦和闭弦相互作用。通过计算伸缩算符的矩阵元，我们再现了N =2 Sp（N）对偶规范理论的所有弦振幅。在弦理论和规范理论的费曼图之间发现了一种直接的图解对应。开+闭弦场论的前因子矩阵和Neumann矩阵分别用规范理论量实现。
We study open and closed string interactions in the type IIB plane wave background using open+closed string field theory. We reproduce all string amplitudes from the dual N =2 Sp(N) gauge theory by computing matrix elements of the dilatation operator. A direct diagrammatic correspondence is found between string theory and gauge theory Feynman diagrams. The prefactor and Neumann matrices of open+closed string field theory are separately realized in terms of gauge theory quantities.
