Mastering the Master Space

Understand

Supersymmetric gauge theories have an important but perhaps under-appreciated notion of a master space, which controls the full moduli space.

• For world-volume theories of D-branes probing a Calabi-Yau singularity X the situation is particularly illustrative.
• In the case of one physical brane, the master space F is the space of F-terms and a particular quotient thereof is X itself.
• We study various properties of F which encode such physical quantities as Higgsing, BPS spectra, hidden global symmetries, etc.
