Researchers set new bounds on the mass of leptoquarks

At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, and quarks, which combine to form protons, neutrons and other composite particles. Under the Standard Model of particle ...

Probing fundamental symmetries of nature with the Higgs boson

Where did all the antimatter go? After the Big Bang, matter and antimatter should have been created in equal amounts. Why we live in a universe of matter, with very little antimatter, remains a mystery. The excess of matter ...

The search for deviations from standard quantum mechanics

Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team led by Philip Walther at the University ...

Counting photons is now routine enough to need standards

Since the National Institute of Standards and Technology (NIST) built its first superconducting devices for counting photons (the smallest units of light) in the 1990s, these once-rare detectors have become popular research ...

New portal to unveil the dark sector of the Universe

Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists catalogued 17 types ...

Fundamental equation for superconducting quantum bits revised

Physicists from Forschungszentrum Jülich and the Karlsruhe Institute of Technology have uncovered that Josephson tunnel junctions—the fundamental building blocks of superconducting quantum computers—are more complex ...
