Particles with two heavy quarks are predicted by the Standard Model theory of particle physics, but this is the first time scientists have been able to confirm they exist.
Public participation is a critical issue for planners of the proposed International Linear Collider. The recent Snowmass conference included a daylong session titled, "Workshop on Public Participation in the ILC," sponsored by the US Linear Collider Communication Committee.
In need of a computer monitor? How about a forklift? Or maybe a sousaphone? If you are working for the US federal government or an approved agency, all this and more is available to your organization—for merely the cost of shipping a few boxes or a crate.
Few facets of nature are more mysterious than the quantum world. Particles that appear and disappear from nothing, interactions governed by probability, and intrinsic uncertainties are enough to baffle even the most experienced scientist.
The amazing properties of spider webs have fascinated scientists for years. Some of the mysteries of the spider's thread (such as the radii and spirals of threads produced by the Nephila pilips spider shown above) are unraveling through the use of synchrotron light sources.
Burton Richter’s group double-checked what they thought was a minor statistical inconsistency in their data. Using the Stanford Positron Electron Accelerating Ring (SPEAR), they probed electron-positron collision energies around 3.1 GeV.
Only detectors with the greatest precision capabilities will measure up to the machine seeking to explore supersymmetry, dark matter, the Higgs mechanism, and new physics that hasn't yet been imagined.
The SLAC archives, in the windowless basement of the Central Laboratory Annex, are no greenhouse. Yet for the past few years, a small tree has adorned the den of SLAC's archivist Jean Deken.
