Inflation models with Peccei-Quinn symmetry and axion kinetic misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a consistent framework with the Peccei-Quinn (PQ) symmetry for obtaining the initial condition for axion kinetic misalignment from inflation. We introduce a PQ co…

Peccei-Quinn Inflation at the Pole and Axion Kinetic Misalignment
Hyun Min Lee, Adriana G. Menkara, Myeong-Jung Seong +1
We propose a minimal extension of the Standard Model with the Peccei-Quinn (PQ) scalar field and explain the relic density of the QCD axion through the kinetic misalignment with a…
