Proton Decay and Gauge Coupling Unification in an Extended SU(5) GUT with 45-Dimensional Higgs
Naoyuki Haba, Keisuke Nagano, Yasuhiro Shimizu +1
We present a comprehensive study of an extended SU(5) grand unified theory (GUT) that incorporates a 45-dimensional Higgs representation to address the shortcomings of the minimal…
Gauge coupling unification and proton decay via 45 Higgs boson in SU(5) GUT
Naoyuki Haba, Keisuke Nagano, Yasuhiro Shimizu +1
We study the gauge coupling unification (GCU) and proton decay in a non-supersymmetric SU(5) grand unified theory (GUT) incorporating a 45 representation Higgs field. Our analysis…
Higgs Portal Majorana Fermionic Dark Matter with the Freeze-in Mechanism
Junpei Ikemoto, Naoyuki Haba, Shimizu Yasuhiro +1
We consider a minimal model of fermionic dark matter, in which the Majorana fermion dark matter (DM) couples with the Standard Model (SM) Higgs field through a higher-dimen…
Moderately Suppressed Dimension-five Proton Decay in a Flipped Model
Naoyuki Haba, Toshifumi Yamada
We study colored Higgsino-mediated proton decay (dimension-five proton decay) in a model based on the flipped GUT. In the model, the GUT-breaking , ${\bf \overline…
Are Low-energy Data already Hinting at Five Dimensions?
Naoyuki Haba, Nobuchika Okada, Toshifumi Yamada
Low-energy data, combined with renormalization group (RG) equations, can predict new physics at far higher energy scales. In this paper, we consider the possibility that the measur…
Renormalizable GUT with Suppressed Dimension-5 Proton Decays
Naoyuki Haba, Yukihiro Mimura, Toshifumi Yamada
We study a renormalizable SUSY GUT model where the Yukawa couplings of single , single and single fields, $Y_{10},Y_{126},Y_{1…
