Open AccessThe cosmological moduli problem and naturalness
Nowadays, the cosmological moduli problem (CMP) comes in three parts: 1. potential violation of Big-Bang nucleosynthesis (BBN) constraints from late decaying moduli fields, 2. the moduli-induced gravitino prob...

Open AccessAffleck-Dine leptogenesis with varying Peccei-Quinn scale
The Affleck-Dine leptogenesis scenario along the LH u flat direction is reconsidered. It is known that successful Affleck-Dine leptogenesis requ...

Peccei-Quinn NMSSM in the light of 125 GeV Higgs
We study the phenomenology of the Peccei-Quinn invariant extension of the next-to-minimal supersymmetric standard model (NMSSM) in view of the recent discovery of a 125 GeV Higgs boson. The minimal model havin...

Effective interactions of axion supermultiplet and thermal production of axino dark matter
We discuss the effective interactions of axion supermultiplet, which might be important for analyzing the cosmological aspect of supersymmetric axion model. Related to axino cosmology, it is stressed that thre...
