The search for neutrinoless double beta decay, ideally in more than one isotope, has been identified as high priority by the international subatomic physics community. Over the past decades, significant advancements have been made in the development of xenon TPCs.

Proposed next-generation experiments intend to deploy tonne(s) of the double beta decaying isotope Xe-136 and are expected to reach sensitivities in the mid-10^27 to 10^28 years range. The complexity of these experiments and the cost of xenon likely will limit the number of next-generation experiments and their timescales.

We are organizing a workshop to discuss possibilities and opportunities for a coherent collaborative effort to search for neutrinoless double beta decay in Xe-136. We want to keep this workshop as inclusive and as broad as possible and are inviting possible collaborators with the aim of creating a new consortium or collaboration under a new name with the broad goal of developing a roadmap for a competitive search for neutrinoless double beta decay using xenon as a target medium.

The workshop will be held November 12-14, 2025 in Montreal.
