Description
Millicharged particles (MCPs) i.e., particles with a small effective charge are a key component of various dark sectors. If these particles exist, they will be produced both in the early universe and in various astrophysical plasmas. The former results in an irreducible density of these particles, the so-called millicharged background, which can be detected using direct detection experiments. The latter can modify stellar evolution and be constrained using astrophysical observations. In this talk, I will discuss how we can constrain the MCP parameter space complementarily using terrestrial and astrophysical probes even and especially in the case where they do not comprise a significant dark matter fraction.
