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…
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…
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…
Asymptotic behavior of a scalar field with an arbitrary potential trapped on a Randall-Sundrum's braneworld: the effect of a negative dark radiation term on a Bianchi I brane
Dagoberto Escobar, Carlos R. Fadragas, Genly Leon +1
In this work we present a phase space analysis of a quintessence field and a perfect fluid trapped in a Randall-Sundrum's Braneworld of type 2. We consider a homogeneous but anisot…
Higgs inflation on the brane
Dagoberto Escobar
We analyze the slow-roll inflation mechanism in brane framework with a real Higgs field confined on the brane. We prove that inflation occur for field value below the 4-dimensional…
