I cant even begin to type out the entire equation for the standard model of particle physics, it is just so immensely long and I don't have the time, energy, or patience to do so. So please excuse the fact that I don't have the equation on here to show exactly what I mean.(adsbygoogle = window.adsbygoogle || []).push({});

Now, I understand most of particle physics and the relations between particles and such, and I understand a good amount of the functions used in the equation. But, I don't understand what all of the symbols and such are for the particles. I can recognize things like photons, gluons, muons, electrons, tau, nuetrinos, muon nuetrinos, tau nuetrinos, W and Z bosons, and Higgs bosons. But, as for other symbols and letters in the equation, I feel like I'm looking at another language entirely. Can someone explain the following symbols, letters and functions:

A, M, u, β, λ, ∂, m, s, c, K, j, X, (the bar over some of the letters and symbols, I don't know what that's for), ϕ, d, Y, and also I don't understand what letters and symbols mean when they are in the form of: W_{u}or W^{k}is.

That's just an example of how the form is used, but I don't understand what it really means.

Please explain this all to me, because I cant find this information anywhere.

Thanks
