论文摘要
在这项工作中，尝试了杂弦理论的NS扇区的两个循环顺序重质量质量的计算。我们首先实施垂直集成处方，以选择一部分，避免使用伪造杆，这是由于所需的图像数量更换的操作员。结果，Riemann表面上的相关幅度可以写为边界项。然后，我们确定了模量空间的1PI区域，因为选择了围绕外部穿刺的粘合局部坐标。我们还确定了边界模块参数的相关集成和相关集成区域。
In this work computation of the renormalised mass at two loop order for the NS sector of heterotic string theory is attempted. We first implement the vertical integration prescription for choosing a section avoiding the spurious poles due to the presence of a required number of picture changing operators. As a result the relevant amplitude on genus 2 Riemann surface can be written as a boundary term. We then identify the 1PI region of the moduli space having chosen a gluing compatible local coordinates around the external punctures. We also identify the relevant integrands and the relevant region of integration for the modular parameters at the boundary.
