key term - Cast

Definition

In the context of dark matter particle candidates, 'cast' refers to the process of modeling or estimating the potential properties and behavior of various hypothetical particles that could make up dark matter. This involves using theoretical frameworks and experimental data to narrow down the range of possibilities for what these particles might be, including their mass, interactions, and production mechanisms. Understanding these properties is crucial for identifying which particles can be detected and studied in experiments.
