- Exploring Majorana landscape: the NEXT generation
- Time: 1:00 pm
- Place: 4274 Chamberlin
- Speaker: Juan JosÃ© GÃ³mez Cadenas, IFIC - Instituto de FÃsica Corpuscular, Valencia, Spain
- Abstract: Neutrinos may be Majorana particles. If so, neutrino less double beta decay processes could be observed by the next generation of bb0nu experiments. I will briefly review the state of the art, then discuss one of the most promising ideas in the field, the use of Hight Pressure Gas Xenon TPC (HPGXe) with electroluminescence gain and optical readout. A 100 kg incarnation of such a device will start operations at the Canfranc Underground Lab in Spain in late 2013 or early 2014. The technology can be extrapolated to 1 ton, and thus lead the exploration of the inverse hierarchy in Majorana landscape.
- Host: Halzen
- Theory Seminar (High Energy/Cosmology)
- Using Singularity for Missing Mass Measurements
- Time: 2:00 pm
- Place: 5280 Chamberlin
- Speaker: Ian-Woo Kim, University of Michigan
- Abstract: We propose a novel generalized method for mass measurements based on the singularity structure of the kinematic phase space that can be applied to any event topology with missing energy. By analyzing the local properties of the observable phase space near a given singularity point, we provide a systematic way to obtain optimized normalized coordinates for the case of interest. Our method subsumes the well-known end-point and transverse mass methods and yields new techniques for studying ``missing particle" events, such as the double chain production of stable neutral particles at the LHC.
- Physics Department Colloquium
- Neutrinos and the Origin of the Elements
- Time: 3:30 pm
- Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
- Speaker: Yong-Zhong Qian, University of Minnesota
- Abstract: Neutrinos are important in driving the expansion of the universe shortly after the big bang and play dynamic roles in supernovae. They also determine the conditions for nucleosynthesis in these two environments. Consequently, big bang and supernova nucleosynthesis is a sensitive probe of the fundamental properties of neutrinos, such as the number of neutrino flavors and the parameters of neutrino oscillations. This talk focuses on the supernova nucleosynthesis probe in view of the recent major advances in experimental studies of neutrino oscillations and in astrophysical observations of elemental abundances. The strong interplay among nuclear, particle physics and astrophysics is emphasized.
