Observational constraints on DBI constant-roll inflation
Abolhassan Mohammadi, Tayeb Golanbari, Khaled Saaidi
Using the constant-roll approach, DBI inflationary scenario will be studied and it is sought to compare the result with observational data. By considering the cosmological perturba…
Constant-roll approach to non-canonical inflation
Abolhassan Mohammadi, Khaled Saaidi, Haidar Sheikhahmadi
The scenario of constant-roll inflation is studied where the inflaton is a scalar field with modified kinetic term, known as non-canonical scalar field. This modification leads to…
Tachyon constant-roll inflation
A. Mohammadi, Kh. Saaidi, T. Golanbari
The constant-roll inflation is studied where the inflaton is taken as a tachyon field. Since in this approach the second slow-roll parameter is assumed to be of order one instead o…
