What is KM3NeT ?

Future cubic-kilometre scale neutrino telescope in the Mediterranean Sea

Exceeds Northern-hemisphere telescopes by factor ~50 in sensitivity

Exceeds IceCube sensitivity by substantial factor

Scientific interest: - Neutrino astronomy (core

energy range: 1 to 100 TeV )

- Dark Matter

- neutrino studies (cross sections, oscillations, …)

- exotics (monopoles, …)

Possible CERN Roles

Recognised experiment (RE)

Structural support with limited resources(reviewing and advisory role)

Structural support with moderate resources(consolidating role in technology and site choices, project organisation etc., member of consortium)

Involvement with significant resources(contribution to preparation and construction,leading member of consortium)
