Marc Schumann elected as XLZD spokesperson

The XENON, LZ and DARWIN collaborations have recently joined forces in the newly established XLZD collaboration. Marc Schumann from Freiburg was elected, together with Dan Akerib from SLAC, as the first spokesperson of the collaboration.

XLZD aims at realizing a future low-background observatory for rare process in astroparticle physics. Its main goal is the search for dark matter in various forms, however, its large 60t liquid xenon target and the very low background level (dominated by irreducible neutrino interactions), will open up a plethora of additional science channels. Prime examples are the search for the lepton-number violating neutrinoless double beta decay of ¹³⁶Xe, a precision measurement of the solar pp-neutrino and the detection of supernovae in our galactic neighbourhood.

The XLZD collaboration has been formed in fall 2024. The elected executive team is now complete. It consists of two co-spokespersons (Dan Akerib, SLAC, and Marc Schumann, Freiburg), the chair of the collaboration board and an executive board of ten members.
