109. Observation of Excess Electronic-Recoil Events in XENON1T

Adam Brown (University of Freiburg)

We present evidence for excess low-energy interactions in the XENON1T detector and discuss possible interpretations. Using a 0.65 t yr exposure, we perform one of the most sensitive searches for solar axions, an enhanced neutrino magnetic moment using solar neutrinos, and bosonic dark matter. We observe an excess of low-energy (1—7 keV) events. A solar axion signal is favoured at 3.4σ over...

48. Axion Quark Nuggets and Matter-Antimatter asymmetry as two sides of the same coin: theory, observations and future experimental searches

Ariel Zhitnitsky (University of British Columbia)

In this talk I want to discuss the (unorthodox) scenario when the baryogenesis is replaced by a charge segregation process in which the global baryon number of the Universe remains zero. In this, the so-called axion quark nugget (AQN) dark matter model the unobserved antibaryons come to comprise the dark matter in the form of dense nuggets. In this framework, both types of matter (dark and...

56. Overview and Status of the LUX-ZEPLIN Experiment

Amy Cottle (University of Oxford)

16/06/2021, 17:40

The LUX-ZEPLIN (LZ) detector consists of a dual-phase xenon time projection chamber designed to directly detect Weakly Interacting Massive Particles (WIMPs) with unprecedented sensitivity, down to a WIMP-nucleon spin-independent cross section of 1.4 x 10^-48 cm^2 for a 40 GeV/c^2 mass in 1000 live days. The experiment is currently in its commissioning phase, with science running expected to...
