Superfield description of 10D SYM theory with magnetized extra dimensions Original Research Article

We present a four-dimensional (4D) image superfield description of supersymmetric Yang–Mills (SYM) theory in ten-dimensional (10D) spacetime with certain magnetic fluxes in compactified extra dimensions preserving partial image supersymmetry out of full image. We derive a 4D effective action in image superspace directly from the 10D superfield action via dimensional reduction, and identify its dependence on dilaton and geometric moduli superfields. A concrete model for three generations of quark and lepton superfields are also shown. Our formulation would be useful for building various phenomenological models based on magnetized SYM theories or D-branes.
