XENON at the 2019 Swiss-Austrian Physical Society Meeting
Five members of the University of Zurich group participated at the 2019 Swiss-Austrian Physical Society Meeting in Zurich, Switzerland. Adam Brown contributed with a poster on the XENONnT upgrades and status and Ricardo Peres on the software for the supernova early warning system: Giovanni Volta, Michelle Galloway and Chiara Capelli contributed with talks on the general XENON1T […]
Search for light dark matter interactions enhanced by the Migdal effect in XENON1T
When a particle elastically scatters off a xenon nucleus, it has been assumed that electron clouds immediately follow the motion of the nucleus, but in reality it takes some time for the atomic electrons to catch up, resulting in ionization and excitation of the atom. This effect is called the Migdal effect, which was predicted by A. B. Migdal and recently reformulated […]
Light Dark Matter Search Results from XENON1T
XENON1T recently released a preprint with new world-leading constraints on light dark matter particles. The challenge of light dark matter The XENON1T detector aims find the signals of dark matter bouncing off xenon atoms. If such a collision happens, it produces two signals: a small light flash (S1), and a cloud of free electrons that […]
XENON talk at Patras Workshop
A talk on the XENON project was given at the 15th Patras Workshop on Axions, WIMPs and WISPs, which was held in Freiburg (Germany) in the first week of June. Andrea Molinario from the Gran Sasso Science Institute and Laboratori Nazionali del Gran Sasso presented the most recent results from the data analysis of XENON1T, […]
XENON on skis
XENON was present at the ALPS conference in Austria. Chiara Capelli from University of Zurich gave a talk on behalf of the XENON collaboration. The talk focused on the latest XENON1T results on spin-independent and spin-dependent WIMPs, and on the newest results on two-neutrinos double electron capture, with a final status on the XENONnT upgrade. […]
Observing the Rarest Decay Process Ever Measured
[Press Release April 2019 – for immediate release. Paper published in Nature and preprint on the arxiv.] The universe is almost 14 billion years old. An inconceivable length of time by human standards – yet compared to some physical processes, it is but a moment. There are radioactive nuclei that wdecay on much longer time […]
Modeling and statistical analysis of the XENON1T data
On May 31st 2018, XENON1T released the result of a search for dark matter interacting with xenon atoms using an exposure of 1 tonne-year. Papers presenting the scientific results are written to be brief, and communicate the most important information to the scientific community. Therefore, many details of the instrument, reconstruction of events and analysis […]
Constraining the spin-dependent WIMP-nucleon interaction with XENON1T
Since we don’t know how dark matter interacts with more familiar particles, we have to break up our search for weakly interacting massive particles (WIMPs) in terms of their possible interactions with xenon nuclei. While many complex interactions are possible, we generally start with two simple cases: WIMP-nucleus interactions that don’t depend on the nuclear […]
