Axion Theory Review
Jihn E. Kim
I review the axion physics with emphases on the couplings of the very light axion and a possible realization in superstring models.
R_F Parity and Almost Massless Up Quark
Jihn E. Kim, Bumseok Kyae, Jae Sik Lee
We introduce a parity to introduce naturally small masses for the first family members and in particular almost massless quark toward the strong CP solution. We also disc…
Large Cosmological Light Element Bound on R Parity Violating Parameters
Jihn E. Kim, Bumseok Kyae, Jong Dae Park
In R parity violating theories, there does not exist the {\it stable} lightest supersymmetric particle (LSP). The LSP, , of MSSM decays to lighter ordinary particles with dimens…
Axion and Almost Massless Quark as Ingredients of Quintessence
Jihn E. Kim
It is pointed out that a natural introduction of quintessence is an axion with an almost massless quark. With an appropriate gauge or discrete symmetry, one can obtain the quintess…
Superstring Axion, Gaugino Condensation, and Discrete Symmetries
Jihn E. Kim
Here I present the effect of gaugino condensation and discrete symmetries to the model-independent axion potential, collaborated with Georgi and Nilles [hep-ph/9805510].
Very Light Axion
Jihn E. Kim
I review the idea of axion, axion properties, and the superstring axion.
