Neutrino Mass: From the Terrestrial Laboratory to the Cosmos

The goal of the workshop is to bring together a small group of theorists, experimentalists, and observers to address the relative implications of terrestrial, astrophysical, and cosmological probes of neutrino mass. With the prospect of order of magnitude improvements in the sensitivities of kinematic mass determinations, two-order of magnitude improvements in the lifetime sensitivity of neutrinoless double beta-decay searches, and significant advances in determinations of the sum of neutrino masses from large scale structure and the CMB, it is timely to delineate what a comparison of results from these, other laboratory and cosmological probes, and simulations might imply.

Among the questions to be addressed are:

1. What are the model assumptions and related uncertainties that enter cosmological determinations of the sum of the light neutrino masses?
2. What early universe physics beyond the Standard Model, if any, might affect this determination?
3. What are the prospective implications of cosmological mass determinations for the interpretation of kinematic mass measurements, neutrinoless double beta-decay searches, and mass hierarchy probes?
4. What are the prospective implications of a positive signal in the next generation kinematic mass and double beta-decay searches for the interpretation of cosmological measurements?
