✦ Synopsis

We report on a calculation of the β-functions for an open string σ-model in the presence of a U (1) background. Passing to N = 2 boundary superspace significantly facilitates the calculation. Performing the calculation through three loops yields the equations of motion up to five derivatives on the fieldstrengths, which upon integration gives the bosonic sector of the effective action for a single D-brane in trivial bulk background fields through four derivatives and to all orders in α ′ .
