Exploring the Landscape of effective field theories

Understand

In this thesis we provide new tools to determine and explore the Landscape of four-dimensional effective field theories originating from string and M-theory.

• The main aim is to introduce, within four-dimensional effective descriptions, elements that are predicted from string theory.
• To this end, a hierarchy of forms is introduced within the four-dimensional $\mathcal{N}=1$ supergravity theories.
• The inclusion of gauge three-forms delivers a dynamical way to generate flux-induced superpotentials.
