Lepton number asymmetries and the lower bound on the reheating temperature
Gabriela Barenboim, Wan-Il Park
We show that the reheating temperature of a matter-domination era in the early universe can be pushed down to the neutrino decoupling temperature at around if the r…
Impact of CP-violation on neutrino lepton number asymmetries revisited
Gabriela Barenboim, Wan-Il Park
We revisit the effect of the (Dirac) CP-violating phase on neutrino lepton number asymmetries in both mass- and flavor-basis. We found that, even if there are sizable effects on mu…
Flavor versus mass eigenstates in neutrino asymmetries: implications for cosmology
Gabriela Barenboim, William H. Kinney, Wan-Il Park
We show that, if they exist, lepton number asymmetries () of neutrino flavors should be distinguished from the ones () of mass eigenstates, since Big Bang Nucleosynthesis…
Gravitational waves from first order phase transitions as a probe of an early matter domination era and its inverse problem
Gabriela Barenboim, Wan-Il Park
We investigate the gravitational wave background from a first order phase transition in a matter-dominated universe, and show that it has a unique feature from which important info…
Eternal Hilltop Inflation
Gabriela Barenboim, William H. Kinney, Wan-Il Park
We consider eternal inflation in hilltop-type inflation models, favored by current data, in which the scalar field in inflation rolls off of a local maximum of the potential. Unlik…
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.
