"Dynamical mu term in gauge mediation"

Speaker: Antonio Delgado, Notre Dame du Lac
When: December 3, 2007 (Mon), 12:30PM to 01:30PM

This event is part of the Particles and Fields Seminar Series. 12:30 PRB 595

Abstract: I will discuss a model in which the mu problem of gauge mediation is addressed by considering a singlet chiral superfield coupled to the Higgs and messenger fields. The experimental bound on the light Higgs boson mass identifies three acceptable regions in the parameter space where the mass spectrum and the collider phenomenology can be distinct from ordinary gauge mediation.
