Everything about a neutrino is a neutrino property! Therefore our working group has strong overlap with all the groups in the neutrino frontier. However, the following areas are centrally within the mandate of this working group:

Direct Neutrino Mass Measurements

• Tritium end-point experiments
• Electron capture experiments
• Any other direct (non-oscillation) methods of neutrino mass measurement

Majorana vs Dirac Fermions

• Neutrinoless double beta decay
• Neutrinoless double electron capture
• Two-neutrino modes
• Majorana phases
• Pseudo-Dirac Neutrinos
• g_A, nuclear matrix elements, etc

Neutrino Electromagnetic Properties

• Charge radius
• Electric dipole moment
• Magnetic dipole moment
• Spin and spin-flavor precession

We will also be considering more esoteric topics like:

• Neutrino lifetime
• Number of active neutrinos
• Gravitational interactions
• Non-oscillation measures of lorentz or CP violation
• etc

And, exploring overlap with other working groups on areas including

• Mixing angles and Δm2 valies
• Mass ordering
• CP violation
• PMNS unitarity / non-unitarity
• Non-standard interactions (in oscillations, CEvNS, or cosmology)
• Lorentz and CPT violation in oscillations
• Coherence properties and quantum gravity connections
• Light sterile neutrinos
• Heavy sterile neutrinos
• Collider searchers for Majorana fermions
• Weak mixing angle
• Astrophysical probes
• Connections to dark energy or dark matter
