We motivate and apply a bottom-up approach to string phenomenology, whichaims to construct the Standard Model as a decoupled world-volume theory on aD3-brane. As a concrete proposal for such a construction, we consider a singleprobe D3-brane on a partial resolution of a del Pezzo 8 singularity. Theresulting world-volume theory reproduces the field content and interactions ofthe MSSM, however with a somewhat extended Higgs sector. An attractive featureof our approach is that the gauge and Yukawa couplings are dual tonon-dynamical closed string modes, and are therefore tunable parameters.Comment: 37 pages, 9 figure
