Warming up the Fibres
Dibya Chakraborty, Rudnei O. Ramos
Fibre inflationary models are constructed in type-IIB string flux compactification. These models have been shown to be in agreement with the cosmological observations under appropr…
Three-Field String Inflation with Perturbative Corrections: Dynamics and Implications
Vasileios Basiouris, Dibya Chakraborty
In this work, we construct an explicit string motivated example of three-field inflation in a related, yet distinct from, the recently discovered perturbative large volume scenario…
Symmetries and Interactions of SUGRA: from Constructive and BCFW to KLT formulations
Dibya Chakraborty, J. Lorenzo Díaz-Cruz, Jonathan Reyes Pérez +1
In this paper, we study the coupling of the gravity supermultiplet (graviton and gravitino) of minimal SUGRA following a constructive approach. Firstly, we use the…
Global Embedding of Fibre Inflation in Perturbative LVS
Swagata Bera, Dibya Chakraborty, George K. Leontaris +1
We present a global embedding of the Fibre inflation model in perturbative large volume scenario (LVS) in which the inflationary potential is induced via a combination of string-lo…
Inflating in perturbative LVS: Global Embedding and Robustness
Swagata Bera, Dibya Chakraborty, George K. Leontaris +1
The perturbative LARGE volume scenario (LVS) is a promising moduli stabilisation scheme in which the overall volume modulus of the compactifying Calabi-Yau (CY) threefold is dynami…
