Title
Precision Physics with Jet Observables
Abstract
The fundamental building blocks of protons, neutrons, pions and atomic nuclei are quarks and gluons, which interact through the strong interaction. The strong interaction, described by the theory of quantum chromodynamics (QCD), confines quarks and gluons into bound states, such that they can never be observed as free particles in a collider experiment. Experimental signatures of quarks and gluons are jets of particles emerging from the interaction region. Jet production observables can be computed from first principles within QCD, and constitute an important tool in particle physics studies. We describe how jet observables can be used for precision measurements in particle physics, and discuss their role at present and future collider experiments.
