The (relative) size does not matter in inflation
Gabriela Barenboim, Wan-Il Park
We show that a tiny correction to the inflaton potential can make critical changes in the inflationary observables for some types of inflation models.
On the tensor-to-scalar ratio in large single-field inflation models
Gabriela Barenboim, Wan-Il Park
We show that generically the tensor-to-scalar ratio in large single-field inflation scenarios is bounded to be larger than for the spectral index in the rang…
Peccei-Quinn field for inflation, baryogenesis, dark matter, and much more
Gabriela Barenboim, Wan-Il Park
We propose a scenario of brane cosmology in which the Peccei-Quinn field plays the role of the inflaton and solves simultaneously many cosmological and phenomenological issues such…
Beyond the Dark matter effective field theory and a simplified model approach at colliders
Seungwon Baek, P. Ko, Myeonghun Park +2
Direct detection of and LHC search for the singlet fermion dark matter (SFDM) model with Higgs portal interaction are considered in a renormalizable model where the full Standard M…
New- vs. chaotic-inflations
Gabriela Barenboim, Wan-Il Park
We show that "spiralized" models of new-inflation can be experimentally identified mostly by their positive spectral running in direct contrast with most chaotic-inflation models w…
Spiral Inflation with Coleman-Weinberg Potential
Gabriela Barenboim, Wan-Il Park
We apply the idea of spiral inflation to Coleman-Weinberg potential, and show that inflation matching well observations is allowed for a symmetry-breaking scale ranging from an int…
