Written by some of the most prominent and active researchers in particle physics, this volume focuses on the first years of data collected at the LHC as well as the experimental and theoretical tools involved. It covers a broad spectrum of activity in particle physics, from the searches for the Higgs boson and physics beyond the Standard Model to studies of quantum chromodynamics, the B-physics sector, and the properties of dense hadronic matter in heavy-ion collisions. The authors also provide examples of real physics analyses using Tevatron data.
