BOOST: A satellite mission to test Lorentz invariance using high-performance optical frequency references

Abstract

BOOST (BOOst Symmetry Test) is a proposed satellite mission to search for violations of Lorentz invariance by comparing two optical frequency references. One is based on a long-term stable optical resonator, and the other is based on a hyperfine transition in molecular iodine. This mission will allow us to determine several parameters of the standard model extension in the electron sector up to 2 orders of magnitude better than with the current best experiments. Here, we will give an overview of the mission, the science case, and the payload.
