    Understanding the Universe from Deep Underground

    Understanding the Universe from Deep Underground Sudbury Neutrino Observatory Art McDonald, Professor Emeritus Queen’s University, Kingston, Ontario, Canada With our laboratory deep underground we have created a very low radioactivity location where we study some of the most basic scientific questions: • How do stars like our Sun burn and create the elements from which we are made? • What are the basic Laws of Physics for the smallest fundamental particles? • What is the composition of our Universe and how has it evolved to the present ? How do you make measurements that can provide answers to enormous questions like these? Answers: 1: Measure elusive particles called NEUTRINOS that come from the deepest reaches of the Sun where the energy is generated and from cosmic rays interacting in the atmosphere. 2: Measure fundamental particles (DARK MATTER) that are left over from the original formation of the Universe. 3. Measure rare forms of radioactivity (DOUBLE BETA DECAY) that can tell us more about fundamental laws of physics. Neutrinos from the Sun The middle of the sun is so hot that the centers of the atoms (nuclei) fuse together, giving off lots of energy and neutrinos. The neutrinos penetrate easily through the dense material in the Sun and reach the earth. Neutrino facts: • Neutrinos, along with electrons and quarks, are basic particles of nature that we do not know how to sub-divide further. • Neutrinos come in three “flavours” (electron, mu, tau) as described in The Standard Model of Elementary Particles, a fundamental theory of microscopic particle physics. •They only stop if they hit the nucleus of an atom or an electron head-on and can pass through a million billion kilometers of lead without stopping.

    Can Tonne-Scale Direct Detection Experiments Discover Nuclear Dark Matter?

    Prepared for submission to JHEP Can Tonne-Scale Direct Detection Experiments Discover Nuclear Dark Matter? Alistair Butcher, Russell Kirk, Jocelyn Monroe and Stephen M. West Dept. of Physics, Royal Holloway University of London, Egham, Surrey, TW20 0EX, U.K. E-mail: [email protected], [email protected], [email protected], [email protected] Abstract: Models of nuclear dark matter propose that the dark sector contains large composite states consisting of dark nucleons in analogy to Standard Model nuclei. We examine the direct detection phenomenology of a particular class of nuclear dark mat- ter model at the current generation of tonne-scale liquid noble experiments, in particular DEAP-3600 and XENON1T. In our chosen nuclear dark matter scenario distinctive fea- tures arise in the recoil energy spectra due to the non-point-like nature of the composite dark matter state. We calculate the number of events required to distinguish these spectra from those of a standard point-like WIMP state with a decaying exponential recoil spec- trum. In the most favourable regions of nuclear dark matter parameter space, we find that a few tens of events are needed to distinguish nuclear dark matter from WIMPs at the 3 σ level in a single experiment. Given the total exposure time of DEAP-3600 and XENON1T we find that at best a 2 σ distinction is possible by these experiments individually, while 3 σ sensitivity is reached for a range of parameters by the combination of the two experiments. We show that future upgrades of these experiments have potential to distinguish a large range of nuclear dark matter models from that of a WIMP at greater than 3 σ.
