Non-perturbative gauge superpotentials from supergravity
Emiliano Imeroni, Alberto Lerda
TL;DR
This paper demonstrates how the non-perturbative superpotential in U(N) SQCD with N_f <= N flavors can be derived from the classical geometry of fractional D3-branes on a specific orbifold, linking gauge theory and supergravity.
Contribution
It provides a geometric derivation of the non-perturbative superpotential in SQCD using supergravity and D-brane configurations, connecting gauge theory moduli space to classical geometry.
Findings
Moduli space emerges from D3-brane geometry
Non-perturbative superpotential is recovered geometrically
Geometric data encodes gauge theory dynamics
Abstract
We study U(N) SQCD with N_f <= N flavors of quarks and antiquarks by engineering it with a configuration of fractional D3-branes on a C^3 / Z_2 x Z_2 orbifold. In particular we show how the moduli space of the gauge theory naturally emerges from the classical geometry produced by the D3-branes, and how the non-perturbatively generated superpotential is recovered from geometrical data.
