Ken-ichi Hikasa, Takaaki Nagano
Some mechanisms of supersymmetry breaking result in splitting of the third generation sfermions from the other sfermions. We show that the three-body decay branching ratio of the l…

Late-Time Entropy Production and Relic Abundances of Neutralinos
Takaaki Nagano, Masahiro Yamaguchi
Many models possess unwanted relics, which should be diluted by entropy production just before the big-bang nucleosynthesis. A field responsible for the entropy production may prod…
