Would anyone care to explain this?

Would anyone care to explain this equation/model to me?

Here is the link:

To be a little more specific, it is on the fourth slide, and is labeled as "The Standard Model Lagrangian".

Can you say WHAT you don't understand?

it is just the kinetic terms and interaction and mass terms for all the particle fields in the standard model, all quarks, leptons, bosons etc.

here is a more compact:
http://en.wikipedia.org/wiki/Standard_model_(basic_details )

the SM Lagrangian is the sum of all those partial Lagrangian, and the fields are vectors to make it more compact notation.

Now in the future, please do better - more descriptive - titles, and also be more specific in the question - the more specific the question is - the more likely is it that you will get response.

Thanks!

And thanks for the advice.
