<p>A new calculation helps narrow down the mass of the W boson, one of the heaviest fundamental particles in the universe</p>
The W boson is a fundamental particle that mediates the weak nuclear force, one of the four fundamental forces in nature. It is responsible for processes like beta decay in atomic nuclei.
Particle mass measurement is a crucial aspect of particle physics, allowing scientists to understand the properties and interactions of fundamental particles. Accurate mass measurements help refine theoretical models in physics.
