Priomordial non-Gaussian features from DBI Galileon inflation
Sayantan Choudhury, Supratik Pal
We have studied primordial non-Gaussian features from a model of potential driven single field DBI Galileon inflation. We have computed the bispectrum from the three point correlat…

Brane inflation: A field theory approach in background supergravity
Sayantan Choudhury, Supratik Pal
We propose a model of inflation in the framework of brane cosmology driven by background supergravity. Starting from bulk supergravity we construct the inflaton potential on the br…

DBI Galileon inflation in background SUGRA
Sayantan Choudhury, Supratik Pal
We introduce a model of potential driven DBI Galileon inflation in background N=1,D=4 SUGRA. Starting from D4- brane-antibrane in the bulk N=2,D=5 SUGRA including quadrat…
