Title: Little Higgs and Spontaneous CP Violation
Abstract: Little Higgs models often feature spontaneously broken extra global symmetries, which must also be explicitly broken in order to avoid massless scalars in the spectrum. Such explicit breaking should not interfere with the requirement of collective symmetry breaking, leading to constraints on model building.
Moreover, it may lead to new sources of CP violation from physical phases in the VEV. We discuss such relation between explicit symmetry breaking and spontaneous CP violation in the context of SU(N)/SO(N) models.
