Illustration of the ion trap used by the ISOLDE team to measure the electron affinity of chlorine. In the trap, chlorine anions are reflected back and forth between two electrostatic ion mirrors, allowing the laser beam (pink) to probe the anions for much longer than in conventional measurements. The laser frequency is tuned to find […]

This is an event seen in the CMS detector with a signature consistent with production of a top quark, a W boson and a Z boson (tWZ). The top quark decays to a b quark and a W boson; the b quark produces a jet and the W decays to two jets. The jets are

Since size is equivalent to energy output for particle colliders, that also means there’s a limit to how energetic we can make them.

From gravity to spin, the science shaping the game can be just as compelling as the action on the field. When the World Series returns to Toronto for Game 6,

The heart of the HOLMES experiment, housed in its gold-plated copper box: an array of 64 TES microcalorimeters, each ion-implanted with ¹⁶³Ho, alongside the microwave multiplexed readout system. The imaged area spans approximately 2 by 3 cm². Credit: Marco Faverzani. In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper

But new research from UBC Okanagan has mathematically proven this isn’t just unlikely—it’s impossible. Dr. Mir Faizal, Adjunct Professor with UBC Okanagan’s Irving K. Barber Faculty of Science, and his international

Every day, we breathe in millions of microscopic particles, including soot, dust, pollen, microplastics, viruses, and synthetic nanoparticles. Some are small

Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Thorium atomic nuclei can be used for very specific precision measurements. This had been suspected for decades, and the search for
