Search For Dark Matter: XENON100 Search Sets Record Limits
2012-07-19 06:09:01

Scientists from the XENON collaboration announced a new result from their search for dark matter. The analysis of data taken with the XENON100 detector during 13 months of operation at the Gran Sasso Laboratory (Italy) provided no evidence for the existence of Weakly Interacting Massive Particles (WIMPs), the leading dark matter candidates. Two events being observed are statistically consistent with one expected event from background radiation. Compared to their previous 2011 result the...

An International team of scientists in the XENON collaboration, including several from the Weizmann Institute, announced on Thursday the results of their search for the elusive component of our universe known as dark matter. This search was conducted with greater sensitivity than ever before. After one hundred days of data collection in the XENON100 experiment, carried out deep underground at the Gran Sasso National Laboratory of the INFN, in Italy, they found no evidence for the existence of...

Scientists leading an underground experiment to discover dark matter may be forced to relocate to a location even deeper below the Earth's surface, according to recent BBC News reports. Cosmic rays are to blame for disrupting the Cryogenic Dark Matter Search II (CDMS II) project, according to BBC Science Reporter Paul Rincon. The CDMS II experiments are currently taking place the Soudan mine in Minnesota, but could be relocated to the SNOLAB facility near Sudbury, Ontario, Canada. As said...

UCLA scientists to discuss XENON100, the newest dark matter detector Dark matter, for more than 70 years as mysterious and unknowable a subject to science as the legendary island of Atlantis has been to history, is bringing 140 scientists from the U.S., Europe and Asia to the Marriott Hotel in Marina del Rey for the ninth UCLA Symposium on Sources and Detection of Dark Matter and Dark Energy in the Universe. The three-day conference runs through Friday, Feb. 26. "Dark matter is one of the...

Even the biggest Star Trek fan would probably have trouble understanding the technical details of the research done by Particle Astrophysics Professor Wolfgang Rau. Professor Rau is the only Canadian researcher among the group of 60 scientists involved in the Cryogenic Dark Matter Search experiment (CDMS) whose latest findings are published in the latest edition of Science magazine. Professor Rau says the project is among the top two or three most important experiments on this subject in the...

Physicists may have glimpsed a particle that is a leading candidate for mysterious dark matter but say conclusive evidence remains elusive. A 9-year search from a unique observatory in an old iron mine 2,000 feet underground has yielded two possible detections of weakly interacting massive particles, or WIMPs. But physicists, who include two University of Florida researchers, say there is about a one in four chance that the detections were merely background noise -- meaning that a worldwide...

The world's deepest underground science lab is being built below the Black Hills of South Dakota. With a depth equal to more than six Empire State buildings, the space is perfectly tailored to the needs of scientists in their quest for mysterious particles known as dark matter. Construction commenced Monday 4,850 feet below the Earth's surface under an abandoned gold mine that once hosted Nobel Prize-winning research. Scientists, politicians and other officials stood by watching. The...

A half-mile down in an old iron ore mine in Minnesota, incredibly sensitive detectors have been waiting for a particle of dark matter, an invisible substance that may form the skeleton of galaxies, to make itself known. A consortium of research scientists, including Stanford physicist Blas Cabrera, anticipated the detection of a predicted-but-undiscovered dark particle known as a weakly interacting massive particle, or WIMP. The hope was that several WIMPs would travel through space and a...

U.S. experiment retakes the lead in competitive race Scientists of the Cryogenic Dark Matter Search experiment today announced that they have regained the lead in the worldwide race to find the particles that make up dark matter. The CDMS experiment, conducted a half-mile underground in a mine in Soudan, Minn., again sets the world's best constraints on the properties of dark matter candidates. "With our new result we are leapfrogging the competition," said Blas Cabrera of Stanford...

Physicists revive bubble chamber technology to search for WIMPs Scientists working on the COUPP experiment at the Department of Energy's Fermi National Accelerator Laboratory today (February 14) announced a new development in the quest to observe dark matter. The Chicagoland Observatory for Underground Particle Physics experiment tightened constraints on the "spin-dependent" properties of WIMPS, weakly interacting massive particles that are candidates for dark matter. Their results, combined...

WIMP -- In astronomy, WIMPs, or weakly interacting massive particles, figure into one explanation of the dark matter problem. The particles are called "weakly interacting" because they seem not to have much interaction with normal matter (electrons, protons, and neutrons) other than gravitational attraction (thus "massive"). Assuming that there are Weakly Interacting Massive Particles, these particles would then fall out of equilibrium with the universe when they are non-relativistic....
