The Belle II experiment has analyzed a small amount of data collected during the start-up phase of SuperKEKB in 2018. The analysis did not provide any indication of the Z' boson, but it did limit the mass and coupling strengths of the particle with previously unattainable accuracy. This result does not rule out the existence of the Z' ...
