Search for New Physics with Atoms and Molecules
read the original abstract
This article reviews recent developments in tests of fundamental physics using atoms and molecules, including the subjects of parity violation, searches for permanent electric dipole moments, tests of the CPT theorem and Lorentz symmetry, searches for spatiotemporal variation of fundamental constants, tests of quantum electrodynamics, tests of general relativity and the equivalence principle, searches for dark matter, dark energy and extra forces, and tests of the spin-statistics theorem. Key results are presented in the context of potential new physics and in the broader context of similar investigations in other fields. Ongoing and future experiments of the next decade are discussed.

Model-independent probes of CP violation in the heavy scalar sector at muon colliders
Observing vector boson fusion production of a heavy scalar followed by decay to Z h1 at muon colliders can establish CP violation in the scalar sector because it requires both h2VV and h2h1Z couplings to be nonzero.
