PHYSICS:
Reports Call for New Super-Accelerator
David Kestenbaum
Two U.S. reports on the state of particle physics released last week say that another collider will be needed if physicists are to assemble a complete picture of the particles and forces that constitute the world. Physicists are asking for one of three very different (and very expensive) devices: a scaled-up Large Hadron Collider, a Next Linear Collider that would smash electrons together, or a device that would collide muons--the electron's short-lived, heavy brothers. Any one of the three would of necessity be an international effort.
