Inflation in String Field Theory

Understand

In this paper, we analyze the inflationary cosmology using string field theory.

• This is done by using the zero level contribution from string field theory, which is a non-local tachyonic action.
• We will use the non-local Friedmann equations for this model based on string field theory, and calculate the slow-roll parameters for this model.
• We will then explicitly obtain the scalar and tensorial power spectrum, their related indices, and the tensor-to-scalar ratio for this model.
