N=3 four dimensional field theories
Iñaki García-Etxebarria, Diego Regalado
We introduce a class of four dimensional field theories constructed by quotienting ordinary SYM by particular combinations of R-symmetry and $SL(2,\mathbb{Z}…
D6-branes and axion monodromy inflation
Dagoberto Escobar, Aitor Landete, Fernando Marchesano +1
We develop new scenarios of large field inflation in type IIA string compactifications in which the key ingredient is a D6-brane that creates a potential for a B-field axion. The p…
On dualities for non-Abelian gauge theories with continuous center
Thomas W. Grimm, Diego Regalado
Formulating gauge theories for gauge groups admitting a continuous center can require to include charged scalars to define a gauge-coupling function. We show that the gauge-fields…
Large field inflation from D-branes
Dagoberto Escobar, Aitor Landete, Fernando Marchesano +1
We propose new large field inflation scenarios built on the framework of F-term axion monodromy. Our setup is based on string compactifications where D-branes create potentials for…
Non-Abelian discrete gauge symmetries in F-theory
Thomas W. Grimm, Tom G. Pugh, Diego Regalado
The presence of non-Abelian discrete gauge symmetries in four-dimensional F-theory compactifications is investigated. Such symmetries are shown to arise from seven-brane configurat…
Yukawa hierarchies at the point of in F-theory
Fernando Marchesano, Diego Regalado, Gianluca Zoccarato
We analyse the structure of Yukawa couplings in local SU(5) F-theory models with enhancement. In this setting the symmetry is broken down to SU(5) by a 7-brane configur…
