On the trail of long-lived particles
When searching for new particles in ATLAS, it is often assumed that they will either decay to observable Standard Model particles at the centre of the detector, or escape undetected, in which case the...

CMS and the continuing quest to unveil dark matter
The search for particles that could constitute dark matter in the universe relies on detecting their interplay with the Standard Model particles through a three-pronged approach: via direct-detection ...

First full jet measurement in Pb–Pb collisions with ALICE
In high-energy collisions at the LHC, quarks and gluons occasionally scatter violently and produce correlated showers of particles, or “jets”. In proton–proton collisions, the rate o...
