Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation.

At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that participants interpreted to imply the existence of a dark matter particle. (more…)

UCLA physicists played prominent role in Nobel Prize-winning Higgs boson research

Two large collaborations of scientists working at the Large Hadron Collider in Switzerland made worldwide news in July 2012 when they announced independent observations of the elusive Higgs boson particle — a discovery hailed as one of the greatest scientific accomplishments of recent decades.

This so-called “God particle” was first postulated some 50 years ago as a crucial element of the modern theory of the forces of nature — it is, physicists say, what gives everything in the universe mass — and it had been the subject of worldwide searches ever since. (more…)

Accelerating a free electron with a laser has been a longtime goal of solid-state physicists.

David Cline, a distinguished professor in the UCLA Department of Physics and Astronomy, and Xiaoping Ding, an assistant researcher at UCLA, have conducted research at Brookhaven National Laboratory in New York and have established that an electron beam can be accelerated by a laser in free space.

This has never been done before at high energies and represents a significant breakthrough, Cline said, adding that it also may have implications for fusion as a new energy source. (more…)
