Description
We derive 4D $\mathcal{N}=1$ supersymmetric effective theory from 10D non-Abelian Dirac-Born-Infeld action compactified on a six dimensional tori with magnetic flux on the D-branes.
For the 10D action, we use a symmetrized trace prescription and focus on the bosonic part.
4D chiral fermions can arise via index theorem for the background flux.
The gauge coupling and the matter K\"{a}hler metric are read from the 10D action, which depend on closed string moduli and the fluxes.
We read the superpotential from an F-term scalar quartic interaction derived from the 10D action, and discuss the contribution of the matter K\"{a}hler metric to the scalar potential is consistent with the supergravity formulation.
