Title: High energy colliders and hidden sectors
Abstract: In this talk I will summarize my work done during toward Ph.D. I will focus most of my efforts on a recent paper where we derived new constraints on light vector bosons coupled gauge symmetries broken by the chiral anomaly. We show that cancellation of the anomaly at a high scale without introducing additional electroweak symmetry breaking into the theory leads to (energy / vector mass)^2 enhanced rates for processes involving the longitudinal mode of the new vector. Taking the example of a vector coupled to baryon number, Z decays and flavor changing neutral current meson decays occur with enhanced rates surpassing previous constraints for a wide range of vector masses.
