Description

Dark Matter makes up ~25% of the energy density of the universe but has yet to be directly detected. Numerous efforts are ongoing to build ever bigger and ever more sensitive detectors to try and detect it. The LUX-ZEPLIN (LZ) experiment, with its 10 tons of liquid xenon, will reach unprecedented sensitivity. However, this can only happen if all potential backgrounds are under control. To make sure of this, and especially to tackle the issue of radon, the most unforgiving background in the experiment, an extensive cleaning and tracking campaign has been underway. In this talk, I will go over the steps that LZ takes in order to estimate, mitigate and get rid of its backgrounds, especially radon.
