我们导出了对 AdS4 × 3 中折叠弦的时空能量的单环修正,该弦在 AdS4 中携带自旋 S,在长弦近似中携带角动量 J 在 3 中。从极限 J << log S 的一般结果中,我们获得了对尖点异常尺寸的单环修正,结果为 -(5log 2)/(2π)。这个值似乎与最近推测的全环 Bethe ansatz 的预测相冲突。
We derive the one-loop correction to the space-time energy of a folded string in AdS4 × 3 carrying spin S in AdS4 and angular momentum J in 3 in the long string approximation. From this general result in the limit J << log S we obtain the one-loop correction to the cusp anomalous dimension which turns out to be −(5log 2)/(2π). This value appears to be in conflict with the prediction from the recently conjectured all-loop Bethe ansatz.
