Martin Bauer coauthored a particle-physics treatment of dark matter with Tilman Plehn. Their calculations connect proposed particle interactions with four distinct tests: cosmological abundance, indirect radiation signals, direct scattering and collider production. A model must relate these through common masses and coupling constants, rather than treating each possible signal independently. The text makes that connection explicit, showing how the same hypothetical interaction can be constrained by very different measurements.^[ref]

Tilman Plehn develops quantitative particle-physics treatments of dark matter. His notes with Martin Bauer connect candidate models with relic abundance, direct detection, indirect detection and collider searches.^[ref]

These are different tests of a proposed interaction. A parameter choice that supplies the cosmological abundance need not automatically evade a scattering experiment or produce a collider signal. Placing the calculations in one framework makes those competing constraints explicit rather than treating “dark matter” as one uniquely specified particle.
