In the search for new forces and interactions beyond the Standard Model, an international team of researchers has now taken a good step forward. The researchers are using an amplification technique based on nuclear magnetic resonance. They use their experimental setup to study a particular exotic interaction between spins: a parity-violating interaction mediated by a new hypothetical exchange particle, called a Z' boson, which exists in addition to the Z boson mediating the weak interaction in the standard Model.
