Description
Dark matter searches now span a wide range of experimental and observational programmes, from collider and fixed-target experiments to direct detection, indirect searches, and cosmological probes. Yet the resulting constraints are often presented in different variables, conventions, and model assumptions, making it difficult to compare them consistently or to build coherent global pictures of viable dark matter and dark sector parameter space. This challenge is especially relevant in cross-field settings, where particle-physics limits, cosmological bounds, and astrophysical constraints must be interpreted side by side.
DarkMatterLive is a collaborative platform designed to address this problem by building and sharing interactive visualisations of dark matter and dark sector constraints in a common, model-aware framework. Based on published experimental and observational results, it brings together limits that are otherwise difficult to compare and, where possible, recasts them into standard variables following widely used benchmark conventions. In this way, the platform helps connect results across particle physics, cosmology, and astrophysics while preserving clear links to the original sources, assumptions, and caveats.
A representative use case is dark photon, where limits on kinetic mixing can be mapped into alternative parameter spaces and compared with complementary constraints from other probes. Hosted on CERN PaaS cloud infrastructure, DarkMatterLive is publicly available through https://darkmatter.web.cern.ch/ web interface, with benchmark plots online and a citable release archived as 10.5281/zenodo.18135859. The framework also interfaces naturally with community resources such as the HEPData portal, helping organise new inputs within a transparent review workflow.
To support broad community use, DarkMatterLive provides a data-ingestion workflow based on CSV curve data and JSON metadata. New results and key reinterpretation and renormalisation factors are documented and peer-reviewed through GitHub pull requests or CERN GitLab merge requests before inclusion. Additional AI-MCP-based ingestion modules are being integrated into the platform workflows. DarkMatterLive is intended as an open tool for connecting particle, astrophysical, and cosmological perspectives on dark matter and dark sector physics, and for enabling more reproducible construction of global constraints across communities.
