Yesterday, scientists from 20 different countries working at CERN, the European Laboratory for Particle Physics, announced that, after years of work, they had created "a new state of matter." In this new state of matter, quarks, the smallest known particles, roam freely instead of being bound up into more complex particles such as protons and neutrons. By smashing heavy lead ions at temperatures...

This website features the ALICE (A Large Ion Collider Experiment) collaboration's aim to "study the physics of strongly interacting matter at extreme energy densities, where the formation of a new phase of matter, the quark-gluon plasma, is expected." The Public section of the website features the construction plan for the detector located at CERN, which will be optimized for heavy-ion physics....

This topic in depth tackles the complex concept of antimatter. First, Wikipedia (1) provides a simple, concise explanation of antimatter and discusses scientists' successes in producing anti-atoms of hydrogen and anti-deuteron nuclei. This online encyclopedia also offers links to many of the physical terms related to the topic so that novices can easily understand the material presented. The...

ZEUS is a collaboration of 450 physicists who are operating a large particle detector at the electron-proton collider HERA at the DESY laboratory in Hamburg. Researchers can find links to the ZEUS physics groups including High Q2, Diffraction and Vector Mesons, and Heavy Flavour Physics. Along with other tasks and components, visitors can learn about the Backing Calorimeter's role in preserving...

FERMILAB's Home Page is the place to go to find out about Top Quark, The Nature of Nature, and Fermilab at Work. The Nature of Nature provides a brief overview of high-energy physics, an article on how scientists do high-eneregy physics, and an article on the benefits of high-energy physics research. There is also access to The Drell Panel Report.

Located at the Oak Ridge National Laboratories, Tennessee, the High Flux Reactor Isotope Facility (HFIR) produces transuranium isotopes for research, industrial, and medical applications. It is also used for a variety of neutron flux experiments. The HFIR Website gives an informative overview of the science and engineering behind the reactor. Visitors can get acquainted with HFIR's history,...

The Interactions.org website serves as a hub for news, information, images, and links for particle physicists. Educators and students can find a sizeable image collection and short videos and animations describing the research and history of key physics institutions. Researchers can discover a global data grid and a database of talks in cosmic physics, linear collider, ethics and science, and...

The Large Electron Positron Collider (LEP) at the Swiss-based European Center for Nuclear Research (CERN) closes its doors for good this month. This is after the LEP experiments produced collisions compatible with the production of the elusive Higgs boson, a theoretical particle thought to be related to the formation of particle mass. Unfortunately for LEP, the new data were too inconclusive to...

NN-Online provides a source for the physics community to access the work of current and former members of the Theoretical High Energy Physics Group of the University of Nijmegen, the Netherlands. The work found here emphasizes the baryon-baryon interaction, including the nucleon-nucleon interaction, hyperon-nucleon interaction, antinucleon-nucleon interaction and pion-nucleon interaction....

Managed by the Universities Research Association, the NuMI (Neutrinos at the Main Injector) Facility and the MINOS (the Main Injector Neutrino Oscillation Search) experiment are part of the US Department of Energy's Fermi National Accelerator Laboratory. This site was created to illustrate the NuMI, which is being designed to produce a beam of neutrinos aimed at the Soudan Underground Mine State...
