The muon system of the CMS experiment (Image: CERN) The CMS collaboration has recently presented new results in searches for long-lived heavy neutral leptons (HNLs). Also known as “sterile neutrinos”, HNLs are interesting hypothetical particles that could solve three major puzzles in particle physics: they could explain the smallness of neutrino masses via the so-called “see-saw” mechanism, they could explain the matter-antimatter asymmetry of the Universe, and at the same time they could provide a candidate for dark matter. They are however very difficult to detect since they interact very weakly with known particles. The current analysis is an example of researchers having to use increasingly creative methods to detect particles that the detectors were not specifically designed to measure. Most of the particles studied in the large LHC experiments have one thing in common: they are unstable and decay almost immediately after being produced. The products of these decays are us ....
“Plasma wakefield acceleration is like surfing,” says Edda Gschwendtner, leader of the AWAKE accelerator R&D project at CERN. AWAKE is all set to begin its second phase of data taking on 31 July – with a brand-new plasma source. While various future collider proposals aim to increase the size of an accelerator to increase the energy of the particles, AWAKE would help to figure out the opposite: how to shrink the size of a particle accelerator while still achieving higher energies, using a new way of accelerating particles. “Imagine a boat on a lake and surfers waiting for a wave. The boat passes by the surfers and creates waves, the surfers jump on the wave and also get accelerated. We do the same in plasma wakefield acceleration. We have plasma (the lake) in which the beam (the boat) drives waves, and then we inject particles (surfers) on the waves to get accelerated,” explains Gschwendtner in her TEDxCERN talk. A plasma wakefield is a type of wave generated by particles ....
