研究了在R对称Wilson线规范场作用下,N=4超Yang-Mills理论在10维Ω背景下的瞬子计算.从背景中瞬子的自洽模型构造出发,得到了变形瞬子的有效作用量。对于一定的情形,我们得到了N=2 π理论在Ω-背景下的有效作用量.我们还研究了D3/D(− 1)-膜系统在R-R3-型场强背景下的低能有效D(− 1)-膜作用量,发现该作用量与Ω-背景下的瞬子有效作用量一致.
We study the instanton calculus for N=4 super Yang–Mills theory in ten-dimensional Ω-background with the R-symmetry Wilson line gauge field. From the ADHM construction of instantons in the background, we obtain the deformed instanton effective action. For a certain case we get the effective action of N=2⁎theory in the Ω-background. We also study the low-energy effective D(−1)-brane action for the D3/D(−1)-brane system in the R–R 3-form field strength backgrounds and find that the action agrees with the instanton effective action in the Ω-background.
