We can now give some more detail about the aforementioned free and interaction terms appearing in the Standard Model Lagrangian density. Any such term must be both gauge and …

This version of the Standard Model is written in the Lagrangian form. The Lagrangian is a fancy way of writing an equation to determine the state of a changing system and explain the …

Our presentation of the standard model does not follow historical lines, since its starting point is the standard model Lagrangian. Yet, its nal form is the result of the inspired work of many …

I am familiar with quantum field theory and the Standard Model, but many parts of the Lagrangian look unfamiliar; what the hell are all the terms? I'll be putting a legend up soon. Again, Veltman …

In these lectures we shall give a short introduction to the Standard Model of particle physics with empha- sis on the electro weak theory and the Higgs sector , and we shall also attempt to …

In the standard model lagrangian, there are three separate gauge groups i.e. SU 3 )c, SU 2 )L and U 1 ( ( ( )Y The subscript c means color, the subscript L means left (because SU 2 here acts …

Going back to the kinetic-gauge terms coming form the covariant derivative of the Higgs elds, if we expand all terms, we notice that there are some additional terms that are quadratic in the …

The Standard Model Lagrangian Abstract The Lagrangian for the Standard Model is written out in full, here. The primary novelty of the approach adopted here is the deeper analysis of the …

Standard Model Lagrangian including neutrino mass terms From An Introduction to the Standard Model of Particle Physics, 2nd Edition, W. N. Cottingham and D. A. Greenwood, Cambridge …

The language that we use to do so is QFT, and the main tool within this framework is the Lagrangian (which depends on fundamental elds and their couplings). Once organized in this …
