High Quality Axion in Supersymmetric Models
Gongjun Choi, Tsutomu T. Yanagida
In this work, we discuss how the use of the symmetries well motivated in physics beyond the Standard model (BSM) can guarantee the high quality axions. We avoid to introduce symmet…
PBH assisted search for QCD axion dark matter
Gongjun Choi, Enrico D. Schiappacasse
The entropy production prior to BBN era is one of ways to prevent QCD axion with the decay constant from overclosing the universe when…
Dynamically Induced Topological Inflation
Gongjun Choi, Weikang Lin, Tsutomu T. Yanagida
We propose an inflation model in which the inflationary era is driven by the strong dynamics of gauge theory. The quark condensation in the confined phase of gauge…
Discrete -symmetry, Various Energy Scales and Gravitational Waves
Gongjun Choi, Weikang Lin, Tsutomu T. Yanagida
We present a supersymmetric model where energy scales of a discrete -symmetry breaking () and cosmic inflation are commonly attributed to the confinement scale of a hidd…
