扭曲场在D-膜和定向褶皱上的散射

Scattering of twist fields from D-branes and orientifolds

Albion Lawrence, Amit Sever

摘要:

本文计算了圆盘和RP 2上Z_N轨道重扭场的两点函数。我们将其应用于计算T^6/Z_3上I型弦论中Kahler势(的对称组合)的O(g_s)修正。这与超对称性有关,即对反常U(1)因子的Fayet-Iliopoulos D项的单圈场相关修正。我们发现这个修正是非零远离orbifold点。

英文摘要:

We compute the two-point function for Z_N orbifold twist fields on the disk and RP2. We apply this to a computation of the O(g_s) correction to the Kahler potential for (the symmetric combination of) blow-up modes in type I string theory on T^6/Z_3. This is related by supersymmetry to the one-loop field dependent correction to the Fayet-Iliopoulos D-term for the anomalous U(1) factor. We find this correction to be non-vanishing away from the orbifold point.
