关于AdS5 × S5中折叠自旋弦的短弦极限

On the short string limit of the folded spinning string in AdS5 x S5

M. Beccaria, A. Tirziu

摘要:

本文将arXiv:0806.4758的结果推广到S^5中角动量J的非零值。在慢短弦近似的特定极限下,我们计算了AdS_5 × S^5中折叠自旋弦能量的单圈修正。在这个极限中,弦在AdS_5的一个近平的中心区域中运动,在AdS_5和S^5中缓慢旋转。单圈修正应该是对SL(2)扇区中Tr D^S Z^J形式的短规范理论算符的反常维数的强耦合展开的第一个次级修正。

英文摘要:

In this paper we generalize the results of arXiv:0806.4758 to non-zero value J of angular momentum in S^5. We compute the 1-loop correction to the energy of the folded spinning string in AdS_5 x S^5 in the particular limit of slow short string approximation. In this limit the string is moving in a near-flat central region of AdS_5 slowly rotating in both AdS_5 and S^5. The one-loop correction should represent the first subleading correction to strong coupling expansion of the anomalous dimension of short gauge theory operators of the form Tr D^S Z^J in the SL(2) sector.
