# A step in the right direction? Analyzing the Wess Zumino Dark Radiation solution to the Hubble tension

@inproceedings{Schoneberg2022ASI, title={A step in the right direction? Analyzing the Wess Zumino Dark Radiation solution to the Hubble tension}, author={Nils Schoneberg and Guillermo Franco Abell'an}, year={2022} }

. The Wess Zumino Dark Radiation (WZDR) model ﬁrst proposed in [1] shows great promise as a well-motivated simple explanation of the Hubble tension between local and CMB-based measurements. In this work we investigate the assumptions made in the original proposal and confront the model with additional independent data sets. We show that the original assumptions can have an impact on the overall results but are usually well motivated. We further demonstrate that the preference for negative Ω k…
