Thermal Leptogenesis in SUSY GUT
Nobuhiro Maekawa, Kei Shibata, Masato Yamanaka
We investigate thermal leptogenesis within a supersymmetric grand unified theory (SUSY GUT) based on the symmetry, where both the doublet--triplet splitting…
Does finetuning make -term contributions smaller in natural grand unified theories with spontaneous supersymmetry breaking?
Nobuhiro Maekawa, Taiju Tanii
In this paper, we explore the natural grand unified theory (GUT) with spontaneous supersymmetry (SUSY) breaking, focusing on the contribution to sfermion and Higgs masses. Natural…
Tension between neutrino masses and gauge coupling unification in natural grand unified theories
Nobuhiro Maekawa, Taiju Tanii
The natural grand unified theories solve various problems of the supersymmetric grand unified theory and give realistic quark and lepton mass matrices under the natural assumption…
Stability of the embedded string in the Higgs model and its application
Yukihiro Kanda, Nobuhiro Maekawa
Since it has been pointed out that physics beyond the Standard Model may be constrained by gravitational waves from cosmic strings, it has been more important to clarify in what ca…
Stability of non-topological string in supersymmetric gauge theory
Yukihiro Kanda, Nobuhiro Maekawa
We construct a non-topological string solution for a supersymmetric gauge theory with gauge symmetry which is spontaneously broken to by developing the va…
Spontaneous SUSY breaking in natural SO(10) grand unified theory
Nobuhiro Maekawa, Yuji Omura, Yoshihiro Shigekami +1
We propose a simple grand unified theory (GUT) scenario in which supersymmetry (SUSY) is spontaneously broken in visible sector. Our model is based on the GUT model that has been p…
