Type IIA Flux Vacua and -corrections
Dagoberto Escobar, Fernando Marchesano, Wieland Staessens
We analyse type IIA Calabi-Yau orientifolds with backgroud fluxes, taking into account the effect of perturbative -corrections. In particular, we consider the -corrections…
Type IIA Flux Vacua with Mobile D6-branes
Dagoberto Escobar, Fernando Marchesano, Wieland Staessens
We analyse type IIA Calabi-Yau orientifolds with background fluxes and D6-branes. The presence of D6-brane deformation moduli redefines the 4d dilaton and complex structure fields…
Phases of Inflation
Gary Shiu, Wieland Staessens
Motivated by the 4d effective field theories for closed string axions in Type II string compactifications with D-branes, we consider chiral gauge theories coupled to multiple axion…
Strong Dynamics and Natural Inflation
Gary Shiu, Wieland Staessens
We continue our investigation of the 4d effective field theory for closed string axions in Type II compactifications with D-branes. The inclusion of Stückelberg couplings for the a…
