Is Heavy Quark Axion Necessarily Hadronic Axion?
Sanghyeon Chang, Jihn E. Kim
We show that heavy quark axion is not necessarily a hadronic axion, which manifests in the quark and lepton seesaw mechanism. We introduce a heavy singlet fermion for each…

Dark Matters in Axino Gravitino Cosmology
Eung Jin Chun, Hang Bae Kim, Jihn E. Kim
It is suggested that the axino mass in the 1 MeV region and gravitino mass in the eV region can provide an axino lifetime of order of the time of photon decoupling. In this case, s…

Neutrino masses from discrete gauge symmetries
Jihn E. Kim, B-A Lindholm
We investigate a model with an extra gauge symmetry in the Standard Model. We assume that only the scalars and the leptons carry non-zero charge. The symmetry gives a struc…
