A Theoretical Framework for R-parity Violation
Minoru Kuriyama, Hiroto Nakajima, Taizan Watari
We propose a theoretical framework for R-parity violation. It is realized by a class of Calabi--Yau compactification of Heterotic string theory. Trilinear R-parity violation in sup…
Supersymmetric Inflation of Dynamical Origin
K. Hamaguchi, K. -I. Izawa, H. Nakajima
Dynamical models of inflation are given with composite inflatons by means of massive supersymmetric gauge theory. Nearly flat directions and stable massive ones in the potential ar…
Inverted Hybrid Inflation as a solution to gravitino problems in Gravity Mediation
H. Nakajima, Y. Shinbara
It was recently found that the decay of inflaton and the SUSY breaking field produces many gravitinos in the gravity mediation scenario. These discoveries led to an exclusion of ma…
Testing the seesaw mechanism at collider energies in the Randall-Sundrum model
Hiroto Nakajima
The Randall-Sundrum model with gauge fields and fermions in the bulk has several attractive features including the gauge coupling unification, a candidate for the dark matter, and…
Solutions to large B and L breaking in the Randall-Sundrum model
H. Nakajima, Y. Shinbara
The stability of proton and neutrino masses are discussed in the Randall-Sundrum model. We show that relevant operators should be suppressed, if the hierarchical Yukawa matrices ar…
