  The first LHC results at 7-8 TeV, with the discovery of a candidate Higgs
boson and the non observation of new particles or exotic phenomena, have made a
big step towards completing the experimental confirmation of the Standard Model
(SM) of fundamental particle interactions. It is thus a good moment for me to
collect, update and improve my graduate lecture notes on Quantum Chromodynamics
(QCD) and the theory of Electroweak (EW) Interactions, with main focus on
Collider Physics. I hope that these lectures can provide an introduction to the
subject for the interested reader, assumed to be already familiar with quantum
field theory and some basic facts in elementary particle physics as taught in
undergraduate courses.
