- Making (gravitational) waves in Switzerland In Switzerland, gravitational waves go a long way. Not only were they predicted by Albert Einstein in his famous general theory of relativity; Swiss researchers have been involved in attempts to detect gravitational waves from the very beginning and are keen to lend their expertise, including from particle physics, to future projects as well. Here’s an update about the current state of research…

- The first version of the SFGDreadout board The first version of the SFGDreadout board arrived in our lab. The new board is a highly complex design done by a collaboration from the LLR (Ecole Polytechnique in France) and the DPNC (Universite de Geneve). The board is capable of reading 256 Silicon PhotoMultipliers using the CITIROC chip in a very compact multilayer design. The electronic card also provides the HV bias voltage and reads the signal from the Silicon PMT's providing a quasi dead-time-free readout in an almost autonomous setup. The boards will be tested by a team from both institutions before launching the full production in September 2022.

- New AMS results on heavy secondary fluorine nuclei show that cosmic rays don't all propagate the same way The Alpha Magnetic Spectrometer (AMS), steadily acquiring cosmic-ray data on the International Space Station (ISS) since May 2011, has measured with percent-level accuracy the spectrum of fluorine nuclei in cosmic rays, providing for the first time the characterization of heavy secondary cosmic-ray spectrum, that is their intensity as function of energy.

- The first CTA Large Size Telescope Detects Very High-Energy Emission from the Crab Pulsar La Palma, Canary Islands, Spain – Between January and February 2020, the prototype Large-Sized Telescope (LST), the LST-1, observed the Crab Pulsar, the neutron star at the centre of the Crab Nebula. The telescope, which is being commissioned on the CTA-North site on the island of La Palma in the Canary Islands, was conducting engineering runs to verify the telescope performance and adjust operating parameters.

- ATLAS produces the first measurement of Higgs production in association with top quarks The ATLAS and CMS experiments at the Large Hadron Collider at CERN have independently observed the production of Higgs bosons in association with two top quarks. The results presented this week at the LHCP conference in Bologna allow for the first time a direct determination of the couplings between top quarks and the Higgs boson. Dr. Stefan Gadatsch from the ATLAS group of Prof. Tobias Golling here at DPNC was one the leaders of the analysis and an editor of the paper.

- Baby MIND detector completed On Feb 16 2018, we completed the heavy installation work for the Baby MIND detector, which is now in its place as it was always meant to be, downstream of WAGASCI. Many thanks to all involved in making this happen. Best regards, Etam on behalf of the installation team pictured in the photo (credit Marat).

- Neutrinos from Nowhere Thanks to the University of Geneva Swiss astroparticle physics participates in IceCube - a huge experiment in neutrino research at the South Pole. The scientists aim to probe with IceCube the exact origin of the neutrinos coming from the universe. For over two years the young scientist Tessa Carver (24) has been part of the experiment.
- Un «chasseur de matière noire» décortique les rayons cosmiques Co-dirigée par l’Université de Genève, la mission DAMPE, chargée de détecter de la matière noire dans l’Univers, fait part de ses premiers résultats scientifques. Jamais détectée, la matière noire est pourtant considérée comme un élément important pour la compréhension et l’étude de nombreux phénomènes dans l’Univers. La mission DAMPE (DArk Matter Particle Explorer), initiée en 2012 par l’Académie des Sciences Chinoises (CAS) en collaboration avec l’Université de Genève (UNIGE) et l’Institut National de Physique Nucléaire d’Italie (INFN), s’est donné pour mission d’en découvrir la trace ; ses premiers résultats scientifques sont publiés aujourd’hui dans la revue Nature. Les données collectées par le satellite révèlent la distribution des particules des rayons cosmiques selon leur énergie : plus l’énergie mesurée est basse, plus les particules sont nombreuses, et inversement. Mais ce qui devait être une courbe régulière présente en réalité une cassure inexpliquée dans le domaine des hautes énergies, autour de 0.9 TeV, à partir duquel les particules sont moins nombreuses qu’attendu. Comprendre cette «rupture de spectre» pourrait nous permettre de remonter jusqu’à la source qui a émis ces particules. Et parmi les sources candidates, l’annihilation ou la désintégration de matière noire.
