Light Gaugino Problem in Direct Gauge Mediation
arXiv:1107.2622 · doi:10.1142/S0217751X11054565
Abstract
It has been known that in a wide class of direct gauge mediation models, the gaugino masses vanish at leading order in SUSY breaking. Recently, this phenomenon is understood in connection with the global structure of vacua in O'Raifeartaigh-type models. We review recent developments on this topic.
