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.

Abstract
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.File in questo prodotto:
