扭二算子的反常维数必须满足由BFKL导出的某些相容性要求。对于N=4 SYM,它表明,在四个循环,来自全循环渐近贝特不等式的反常尺寸不通过这个测试。在本文中,我们获得了剩余的包装部分,这些异常尺寸从弦理论,并表明,这些贡献完全治愈的问题,并导致与LO和NLO BFKL的预期协议。
The anomalous dimensions of twist two operators have to satisfy certain consistency requirements derived from BFKL. For N=4 SYM it was shown that at four loops, the anomalous dimensions derived from the all-loop asymptotic Bethe ansatz do not pass this test. In this paper we obtain the remaining wrapping part of these anomalous dimensions from string theory and show that these contributions exactly cure the problem and lead to agreement with both LO and NLO BFKL expectations.
