DØ, A High Energy Physics Experiment and Its Computing Grid

High Energy Physics is a discipline of physics that pursues the understanding of fundamanetal building blocks of nature and the forces between them. The DØ experiment is a general purpose High Energy Physics experiment at Fermi National Accelerator Laboratory in the US.

One of the primary goals of the experiment is discovery of the Higgs particle, believed to be the manifestation of a mechanism that gives masses to particles. The experiment has been taking data for approximately two years. Since anticipated total data size approaches to a Peta-byte (10**6 Giga-bytes), and the collaboration is world-wide, effective sharing of data for expeditious physics analyses is an utmost challenge. For this reason, an architecture based on the popular computing Grid concept has been proposed and is being implemented throughout the world.

In this presentation, I will describe the current status of the experiment and its progress in physics analyses. I will then describe the concept of the DØ computing Grid archetecture and the status of its implementation.
