MADISON – When the world’s most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions. Researchers from the ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

UPTON, NY—Given the choice of three different “spin” orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher at the U.S. Department of ...

For more than a decade, physicists have argued (and counter-argued) that a subatomic particle can be separated from certain quantum properties, such as its spin—a phenomenon known as the Cheshire cat ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, ...

Exotic spin-dependent interactions represent a promising avenue for probing physics beyond the Standard Model. These interactions, hypothesised to be mediated by new light bosons, couple to the ...

Scientists on the ATLAS experiment explored the polarization of W bosons to test the Higgs mechanism and gain a deeper understanding of the first moments after the Big Bang. After the Big Bang, the ...

Electrons are proficient little magicians. They seem to flit about an atom without tracing a particular path, they frequently appear to be in two places at once, and their behavior in silicon ...

Given the choice of three different 'spin' orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher, appear to have a preference. Recent ...

Spin orientation preference may point to a previously unknown influence of the strong nuclear force—and a way to measure its local fluctuations. Certain particles that emerge from a hot soup of matter ...
