Orbifold Compactification and Related Phenomenology
Kyuwan Hwang, Jihn E. Kim
In this lecture, starting with GUT we go through the field theoretic and stringy orbifold compactification of extra dimensions toward their application to low energy particle physi…
Completing Natural Inflation
Jihn E. Kim, Hans Peter Nilles, Marco Peloso
If the inflaton is a pseudo-scalar axion, the axion shift symmetry can protect the flatness of its potential from too large radiative corrections. This possibility, known as natura…
A New Mechanism For Baryogenesis Living Through Electroweak Era
Hyung Do Kim, Jihn E. Kim, Takuya Morozumi
We present a new mechanism for baryogenesis by introducing a heavy vector-like SU(2)_W singlet quark(s) with Q_{em}=2/3 quark U or Q_{em}=-1/3 quark D. The lifetime of the heavy qu…
Self-tuning of the cosmological constant and Einstein Gravity on the brane
Jihn E. Kim, Bumseok Kyae, Qaisar Shafi
We show that a self-tuning mechanism of the cosmological constant could work in 5D non-compact space-time. The standard model matter fields live only on the 4D brane. The change of…
Self-tuning of cosmological constant and exit from inflation
Jihn E. Kim
I review the recent 5D self-tuning solutions of the cosmological constant problem, and try to unify two cosmological constant problems within the framework of the self-tuning solut…
