(Extra)Ordinary Gauge/Anomaly Mediation
Tatsuo Kobayashi, Yuichiro Nakai, Manabu Sakai
We study anomaly mediation models with gauge mediation effects from messengers which have a general renormalizable mass matrix with a supersymmetry-breaking spurion. Our models lea…
Inflation in Gauge Mediation and Gravitino Dark Matter
Kohei Kamada, Yuichiro Nakai, Manabu Sakai
We present an inflationary scenario based on a phenomenologically viable model with direct gauge mediation of low-scale supersymmetry breaking. Inflation can occur in the supersymm…
Higgs Portal to Visible Supersymmetry Breaking
K. -I. Izawa, Yuichiro Nakai, Takashi Shimomura
We propose a supersymmetric extension of the standard model whose Higgs sector induces a spontaneous supersymmetry breaking by itself. Unlike the minimal extension, the current Hig…
Comments on Gaugino Mass and Landscape of Vacua
Yuichiro Nakai, Yutaka Ookouchi
In direct gauge mediation, gaugino masses often vanish at the leading order of supersymmetry breaking. Recently, this phenomenon is understood in connection with the global structu…
