Correlation Between Proton Decay Channels and the Axion Mass in an Extended SU(5) GUT
Naoyuki Haba, Keisuke Nagano, Yasuhiro Shimizu +1
We study a renormalizable SU(5) grand unified theory (GUT) supplemented by a 45-dimensional Higgs field and a DFSZ axion sector, imposing a Georgi--Jarlskog flavor structure at the…

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…

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…
