Outline
W boson is the elementary bosonic particle mediating the weak force and its mass is originated from electroweak symmetry breaking. Precision measurements of W boson mass provide a self-consistence check of the standard model theory and could hint at new particles or other mysteries of physics yet to be discovered. The Fermilab CDF group published the most precise result on W boson mass and found that this new measurement disagreed with the standard model's expectation by 7 sigma on the statistical significance. This finding would possibly challenge the current understanding of the standard model of particle physics.
