The full 2013 CETUP* Agenda will be announced at a later date

Neutrino Physics and Astrophysics

Solar, accelerator, and reactor experiments performed during the last two decades firmly established that neutrinos mix. The last remaining mixing angle θ13 was recently measured and is likely to be the best known neutrino mixing angle as the reactor based experiments continue taking data. However many questions remain. One of the goals of the neutrino part of CETUP* meetings is to assess, study and compare models to understand measured large values of the mixing angles and to identify strategies to measure remaining neutrino parameters. Among those remaining parameters the mass hierarchy provides crucial input to the neutrinoless double beta decay and the role of neutrinos in the dynamics of core-collapse supernovae. The other remaining neutrino parameter, namely the CP-violating phase is planned to be studied with the LBNE experiment, currently under consideration.

One way to interpret a number of the anomalous results in neutrino physics is to invoke light sterile neutrinos. Such light sterile neutrinos would also play an important role in cosmology and astrophysics.

Although we have a fairly good idea about neutrino mass differences, absolute values of the neutrino masses are still unknown. Another goal of the workshop would be to develop strategies to measure absolute values of neutrino masses.

Neutrinos form an intellectual bridge between particle physics and astrophysics/cosmology. CETUP* aims for a dialogue between practitioners in both fields leading to better understanding of what each field have to offer. One example that would benefit from a critical analysis is the precise nature of the relation between effective neutrino number parameter in cosmology and the number of neutrino flavors (including sterile neutrinos) in the extensions of the Standard Model.

Leading theoretical physicists from around the world will converge in Lead, SD this summer, for intense discussions on the theory of neutrino masses, the phenomenology of neutrino oscillations, and tests of unified theories in underground experiments.
