Abstract
:Small field models of inflation have previously thought to be
disfavored by the CMB data, in the context of gravitational wave (GW)
signal generation. Ben-Dayan and Brustein have introduced models that,
contrary to popular wisdom, are able to to yield significant GW
signature, while conforming to known CMB observables (2010). While
based on solid arguments, the work presented, shows the model building
technique used by Ben-Dayan, Brustein and others, to rely on ill-suited
assumptions. These assumptions are codified in the Stewart-Lyth
analytic expression (1993), which is commonly used. The work presented
shows these to break due to e-fold hierarchy breakdown and other
issues. Additionally, we find new small field candidates of the
Ben-Dayan&Brustein variety that are precisely calculated and yield
r=0.001 while conforming to known CMB observables, thus reviving the
model.
