  The European School of High-Energy Physics is intended to give young
physicists an introduction to the theoretical aspects of recent advances in
elementary particle physics. These proceedings contain lecture notes on quantum
field theory and the Standard Model, quantum chromodynamics, flavour physics,
neutrino physics, physics beyond the Standard Model, cosmology, heavy ion
physics, statistical data analysis, as well as an account for the physics
results with the data accumulated during the first run of the LHC.
