- Abstract:
Students use conservation of momentum to calculate the mass of the top quark. This activity examines the fingerprint of a top/antitop production that took place in the D-Zero Detector at Fermilab on July 9, 1995. This activity will build on student understanding of vector addition and depends upon only a small amount of particle physics explanation.

- Abstract:
These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.

- Abstract:
This class will study some of the changing ideas within modern physics, ranging from relativity theory and quantum mechanics to solid-state physics, nuclear and elementary particles, and cosmology. These ideas will be situated within shifting institutional, cultural, and political contexts. The overall aim is to understand the changing roles of physics and of physicists over the course of the twentieth century.

- Abstract:
This site introduces, through an interactive adventure tour, the theory of fundamental particles and forces. It also looks at why physicists want to go beyond the Standard Model theory.

- Abstract:
The strong force which bind quarks together is described by a relativistic quantum field theory called quantum chromodynamics (QCD). Subject surveys: The QCD Langrangian, asymptotic freedom and deep inelastic scattering, jets, the QCD vacuum, instantons and the U(1) problem, lattice guage theory, and other phases of QCD. Strong Interactions is a course in the construction and application of effective field theories, which are a modern tool of choice in making predictions based on the Standard Model. Concepts such as matching, renormalization, the operator product expansion, power counting, and running with the renormalization group will be discussed. Topics will be taken from heavy quark decays and CP violation, factorization in hard processes (deep inelastic scattering and exclusive processes), non-relativistic bound states in field theory (QED and QCD), chiral perturbation theory, few-nucleon systems, and possibly other Standard Model subjects.
