Catch-me-if-you-can: the overshoot problem and the weak/inflation hierarchy

Abstract:

We study the overshoot problem in the context of post-inflationary string cosmology (in particular LVS). LVS cosmology features a long kination epoch as the volume modulus rolls down the exponential slope towards the final minimum, with an energy density that scales as m 4s. It is a known fact that such a roll admits attractor tracker solutions, and if these are located the overshoot problem is solved. We show that, pr...
