Vector dark matter, inflation and non-minimal couplings with gravity
Ogan Özsoy, Gianmassimo Tasinato
We propose a cosmological dark matter production mechanism in the form of a longitudinal massive vector boson. We build upon the work of Graham et.al. including non-minimal couplin…
How Well Can We Really Determine the Scale of Inflation?
Ogan Özsoy, Kuver Sinha, Scott Watson
A detection of primordial B-modes has been heralded not only as a smoking gun for the existence of inflation, but also as a way to establish the scale at which inflation took place…
Non-thermal Histories and Implications for Structure Formation
JiJi Fan, Ogan Ozsoy, Scott Watson
We examine the evolution of cosmological perturbations in a non-thermal post-inflationary history with a late-time matter domination period prior to BBN. Such a cosmology could ari…
Heavy Gravitino and Split SUSY in the Light of BICEP2
JiJi Fan, Bithika Jain, Ogan Ozsoy
High-scale supersymmetry (SUSY) with a split spectrum has become increasingly interesting given the current experimental results. A SUSY scale above the weak scale could be natural…
