Abstract
摘要 |
A CHY representation for off-shell scalar tree diagrams is presented. From this ANY loop diagram can be obtained just by folding the appropriate off-shell legs. In this way one avoids using higher-genus worldsheets in the string formulation. Simple examples are given to illustrate these rules. |
