Hi Everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I have to calculate the coefficients of the massive Higgs Lagrangian in natural units, ħ = c = 1.

Do I assume firstly that, in these units the masses of the Higgs, W and Z are the usual,

125.09±0.21, 80.4, 91.2 respectively, and secondly that e has to have the value 2√(απ), where α is the Fine Structure Constant? This seems to make sense.

Please tell me if these values are correct and if not, what the values are and how they come about.

Your assistance will be greatly appreciated!

Have fun with Physics!
