Now bear with me, I'm no expert when it comes to Electroweak Symmetry and Symmetry Breaking; I can only comprehend up to integrating, functions, derivatives, partial derivatives with a small hint of linear algebra and the basic, Hermitian, Hamiltonian, bras and kets.(adsbygoogle = window.adsbygoogle || []).push({});

So my questions are the following:

A.) What do all the symbols mu, tau, nu, etc mean when they are on top and/or below the B particle symbol and the W boson symbol?

B.) What is a covariant derivative?

C.) What is Yukawa Interaction?
