Why did Peter Higgs, et al. suspect that the $W$ boson(s) had mass? All the way back in 1963, '64?

Already in 1957, Julian Schwinger, Annals of Physics 2 (5) November 1957, pp 407-434, "A theory of the fundamental interactions", had inferred from the chiral structure and puny strength ...

Different representations of the Yukawa interaction

Your second expression is meaningless. You need to saturate a row vector with a column vector, not to mention the spinor implicit index saturation, so it should be, instead, $$y_e \bar{e}_R H^\dagger ...

Custodial symmetry of the standard model symmetry group $SU(2)_L \times SU(2)_R$

I have included 5 links, including a "primary" one, which should help clear up the trail map for you; I think you've gone off it, but I can't be sure, as weird misconceptions have crept in. ...

Why did Peter Higgs, et al. suspect that the $W$ boson(s) had mass? All the way back in 1963, '64?

In 1961, Sheldon Lee Glashow already published his paper with the correct EW symmetry group SU(2)$\otimes$U(1) and hypothesized the W and Z bosons. The question, traced back to Julian Schwinger (...
