We initiate a comprehensive investigation of the geometry of the amplituhedron, a recently found geometric object whose volume calculates the integrand of scattering amplitudes in planar N = 4 SYM theory. We do so by introducing and studying its stra... Read More about Anatomy of the amplituhedron.

On axion monodromy inflation in warped throats (2015)
Journal Article
Franco, S., Galloni, D., Retolaza, A., & Uranga, A. (2015). On axion monodromy inflation in warped throats. Journal of High Energy Physics, 2015(2), Article 86. https://doi.org/10.1007/jhep02%282015%29086

Recent models of axion monodromy inflation in string theory link the inflationary potential and the moduli stabilization potential. Realistic inflationary models require mechanisms to moderately suppress the inflaton mass with respect to the moduli s... Read More about On axion monodromy inflation in warped throats.

The geometry of on-shell diagrams (2014)
Journal Article
Franco, S., Galloni, D., & Mariotti, A. (2014). The geometry of on-shell diagrams. Journal of High Energy Physics, 2014(8), Article 38. https://doi.org/10.1007/jhep08%282014%29038

The fundamental role of on-shell diagrams in quantum field theory has been recently recognized. On-shell diagrams, or equivalently bipartite graphs, provide a natural bridge connecting gauge theory to powerful mathematical structures such as the Gras...

Non-supersymmetric meta-stable vacua from brane configurations (2007)
Journal Article
Franco, S., García-Etxebarria, I., & Uranga, A. (2007). Non-supersymmetric meta-stable vacua from brane configurations. Journal of High Energy Physics, 2007(01), Article 085. https://doi.org/10.1088/1126-6708/2007/01/085

We construct configurations of NS-, D4-, and D6-branes in type IIA string theory, realizing the recently discussed non-supersymmetric meta-stable minimum of 4d = 1 SU(Nc) super-Yang-Mills theories with massive flavors. We discuss their lift to M-theo... Read More about Non-supersymmetric meta-stable vacua from brane configurations.
