LSST DESC Theory & Joint Probes Working Group

This summer, the Dark Energy Science Collaboration (DESC) wrote a Science Roadmap (SRM) detailing the key projects and deliverables required to have the DESC analysis pipeline in place to undertake a dark energy analysis. I will provide an overview and user guide to the SRM to make this document more accessible. I will then give a broad introduction to the different lines of research developed in the Theory and Joint Probes working group within DESC, and highlight potential topics for exchange and collaboration with the broader DESC community.
