Wednesday 3 February 2016 Speaker: Claudio Coriano (Salento University) Title: "Z' models from the GUT to the LHC scale" Abstract: In this talk I will present a brief introduction to the physics of extra Z prime, focusing on theoretical issues but formulated for an experimental audience. Extra Z prime are ubiquitous, but some of them are more likely to grasp the attention of model builders. I will then turn to highlight one specific model, which is accompanied by an axion.
