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…
