We compare the gauge fixed Abelian Dirac-Born-Infeld action with string amplitudes in presence of a constant magnetic background in order to find the mapping between QFT polarizations and string polarizations, and to extract the gauge suggested by string theory in presence of a constant magnetic background, which generalizes the Gervais–Neveu gauge.

Gervais-Neveu 测量仪在恒定磁场背景下

我们将规范固定的 Abelian Dirac-Born-Infeld 作用与存在恒定磁场背景下的弦振幅进行比较，以找到 QFT 极化和弦极化之间的映射，并在存在恒定磁场的情况下提取弦理论建议的规范背景，它概括了 Gervais-Neveu 规范。
