D2.00001: Theta-13 Measurements Invited Speaker: Zelimir Djurcic The current precise measurements of $\theta_{13}$ originate from reactor anti-neutrino disappearance measurements Double Chooz, Daya Bay, and RENO, as well as from accelerator neutrino appearance experiments MINOS and T2K. In this talk I will cover the experimental results and describe how we went from recently unknown value of this mixing parameter and suddenly ended up with a very precise quantity. I will also describe the standard neutrino oscillation framework and the role that $\theta_{13}$ provides as a critical input for experiments planning to measure CP-violating phase $\delta$ and the neutrino mass hierarchy.

D2.00002: Status and Future of Double Beta Decay Invited Speaker: Carter Hall Now that the origin of electroweak symmetry breaking is being revealed at the LHC, it is a good time to review where we stand with respect to the origin of neutrino mass. Our best tool for addressing this question is the neutrinoless double beta decay of heavy nuclei. This process, if it exists, would violate the conservation of lepton number by two units, and would measure the absolute scale of the neutrino mass spectrum. But most importantly, double beta decay could give us a window on the non-standard model physics that gives rise to the tiny neutrino masses that we find in nature. In the last two years a new generation of double beta decay experiments has started taking data and producing results, and several more will join them in the near future. It is conceivable that these experiments could report a discovery in the next few years. Meanwhile, on the theory side, a variety of techniques are being applied to the problem of the nuclear matrix elements. These calculations will guide us to the underlying physics, if an experimental observation is made. This talk will review the current status of the double beta decay field and its likely direction in the coming years. [Preview Abstract] |

D2.00003: Neutrinos: the next steps Invited Speaker: Kate Scholberg Progress in neutrino physics over the past two decades has been tremendous, but there are questions yet to answer. This talk will survey experimental opportunities worldwide that can address these questions in the next decade and beyond. [Preview Abstract] |
