Big-bang nucleosynthesis with a long-lived CHAMP including He4 spallation process
Toshifumi Jittoh, Kazunori Kohri, Masafumi Koike +4
We propose helium-4 spallation processes induced by long-lived stau in supersymmetric standard models, and investigate an impact of the processes on light elements abundances. We s…
Minimal Dilaton Model
Tomohiro Abe, Ryuichiro Kitano, Yasufumi Konishi +3
We construct a minimal calculable model of a light dilaton based on the scenario where only top and Higgs sectors are involved in a quasiconformal dynamics. The model consistently…
Allowed slepton intergenerational mixing in light of light element abundances
Kazunori Kohri, Shingo Ohta, Joe Sato +2
We studied allowed region on the intergenerational mixing parameters of sleptons from a viewpoint of big-bang nucleosynthesis in a slepton-neutralino coannihilation scenario. In th…
