XENON at EPS-HEP2019
XENON was on the agenda at the European Physical Society Conference on High Energy Physics 2019 (EPS-HEP2019), which was held in Ghent, Belgium in the middle of July. The talk, presented by Adam Brown from the University of Zurich group, concentrated on results from XENON1T and also provided an overview of the work which is […]
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, […]
XENON1T talk at Low Radioactivity Technique 2019
Our latest XENON1T paper on details of our analysis was presented at the Low Radioactivity Techniques, a conference focused on low background experiments. In the talk (that you can find here), the response model of the detector, the challenges of background modeling, as well as the used techniques were described. In a low background experiment […]
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 […]
Latest XENON1T results at ICHEP2018 in Seoul
The XXXIX International Conference on High Energy Physics (ICHEP2018) was taking place from July 4 – 11, 2018 in Seoul, Korea. After a warm welcome in this modern and traditional metropolis with over 10 million citizens, I was invited to present the recent results from XENON1T in a Dark Matter parallel session. Here is one […]
XeSAT2017: Online krypton and radon removal for the XENON1T experiment
This talk by Michael Murra (slides) was presented at the XeSAT2017 conference in Khon Kaen, Thailand, from 3. – 7. April 2017. The main background for the XENON1T experiment are the intrinsic contaminants krypton and radon in the xenon gas. Instead of purifying the xenon once before starting the science run we were able to […]
