An Alternative for Moduli Stabilisation - RTN Workshop 2006

D3-branes

In the last few years we have witnessed an increasing

activity in the search of ways to stabilise moduli

In general, most of the constructions involve non-trivial

fluxes for NS-NS and R-R potentials

fluxes

CY

H3 ∧ F3

generate the superpotential

[Gukov,Witten]

Ω ∧ (F3 + τH3)

fixes the complex structure moduli

[Giddings,Kachru,Polchinski]
