Title: Cosmological Aspects in Direct Gauge Mediation
Date (JST): Wed, Sep 22, 2010, 13:30 - 14:30
Place: Seminar Room A
Abstract: A Landau-pole free controllable direct gauge mediation model is highly predictive and reliable in a wide range of energy scale. I will discuss some cosmological aspects of such models, especially focusing on a global symmetry in vector-like models. I will show a possibility of proving the hidden sector by gravitational wave generated by a cosmic string in future experiment. Also, I will discuss a connection between gaugino mass and the landscape of vacua in various gauge mediation models.
