AdS(4)× CP(3)弦及其近平面波极限下的Bethe方程

The AdS(4) x CP(3) string and its Bethe equations in the near plane wave limit

Per Sundin

摘要:

我们在$AdS_4 \times CP_3$的大光锥动量/近平面波极限下对玻色IIA型弦论进行了详细的研究。为了实现这一点,我们推导出的哈密顿量的三次和四次的领域和计算的能量为弦激发的$R\times S^2 \times S^2$子空间。弦能量的计算是利用幺正变换,使我们能够删除三次项的哈密顿量的任意长度的激发。然后,我们重写了一组最近提出的所有循环贝特方程的光锥语言,并比较他们的预测与得到的弦能量。我们找到了完美的协议。

英文摘要:

We perform a detailed study of bosonic type IIA string theory in a large light-cone momentum / near plane wave limit of $AdS_4 \times CP_3$. In order to attain this we derive the Hamiltonian up to cubic and quartic order in number of fields and calculate the energies for string excitations in a $R\times S^2 \times S^2$ subspace. The computation for the string energies is performed for arbitrary length excitations utilizing an unitary transformation which allows us to remove the cubic terms in the Hamiltonian. We then rewrite a recent set of proposed all loop Bethe equations in a light-cone language and compare their predictions with the obtained string energies. We find perfect agreement.
