IPPP Workshop on Neutrinoless Double Beta Decay Phenomenology Grey College, Durham, UK April 21-23, 2004

Within the Standard Model, neutrinoless double beta decay (0νββ) is forbidden; lepton number is violated. However, recent neutrino oscillation experiments strongly suggest that neutrinos are, in fact, massive particles and that the description of neutrinos within the Standard Model is not complete. To move beyond the Standard Model and formulate a new theoretical framework with which to describe neutrino phenomenology, the mass mechanism must be investigated. 0νββ experiments illuminate the nature of the mass term in the neutrino Lagrangian; if 0νββ is observed, the neutrino must be a Majorana particle. This represents both theoretical and experimental challenges. The rate of decay via 0νββ will give a value for the absolute scale of neutrino mass. in contrast to neutrino oscillation experiments which only allow the mass differences between the different neutrino flavours to be probed. The UK has a strong and growing interest in 0νββ experiments, and a strategy document has recently been produced.

The Workshop will focus on the physics of 0νββ, covering both the status of and prospects for the nuclear matrix element calculations that are a key factor in extracting information on the neutrino masses, and also what a signal would imply for physics beyond the Standard Model.

The Workshop will take place at Grey College, within walking distance of the historic site of Durham Castle and Cathedral. It will start at lunchtime on Wednesday 21st April and end on lunchtime on Friday 23rd April 2004. The fee is £130 which covers administration costs, secretarial costs, conference facilities and the conference banquet, plus full board accommodation for the duration of the conference at Grey College.
