In a series of pages, I explain how the Standard Model and its Higgs field work to give masses to the W and Z bosons, and how the triplet variant of the Standard Model can shift the W mass [see also here] but leave everything else (except the Higgs boson) unchanged. The pages are linked below; they also sit below this one in the drop-down menu. Some pre-university math is required, such as trigonometry and complex numbers, but nothing beyond that.
