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.

T2K published in March 2020 the first indication of possible violation of the symmetry between neutrinos and antineutrinos in oscillations.

The Alpha Magnetic Spectrometer (AMS) installed on the International Space Station since May 2011 has measured with percent-level accuracy the spectrum of iron nuclei in cosmic rays, providing for the first time the characterization of these very heavy cosmic-ray component.

Dr. Steven Schramm of the Department of Nuclear and Corpuscular Physics (DPNC) has obtained an SNF Eccellenza Professorial Fellowship in support of his project titled “Turning noise into data: a discovery strategy for new weakly-interacting physics.”

Dr. Steven Schramm of the Department of Nuclear and Corpuscular Physics (DPNC) has obtained an ERC Starting Grant providing funding of up to € 1.5 million over five years, for the DISCOVERHEP project (Turning noise into data: a discovery strategy for new weakly-interacting physics).

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.

Mme Dalila Salamani, Doctorante au DPNC a reçu le 2ème prix du Jury.

The experiment, which will complement existing searches for dark matter at the LHC, will be operational in 2021

Researchers at UNIGE have discovered that photons emitted during the creation of a black hole appear to be disordered. Within a single time slice they however appear to be highly ordered.

Hyper-Kamiokande Experiment to Begin Construction in April 2020

The second phase of the TrackML tracking machine learning challenge has just started and you are invited to participate and contribute.

Exciting news about #IceCubeNeutrinos and #MultimessengerAstronomy!

Le DPNC participe à la Nuit de la Science. Expérimentons-nous avec la physique des particules !

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.

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).

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.

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.

On 14 September 2015, the universe's gravitational waves were observed for the very first time.

The MOOC « Particle Physics – an Introduction » is now available in French as well as in English. This course introduces you to subatomic physics, i.e. the physics of nuclei and particles.
