${{\mathit \nu}}$ MASS (electron based)

INSPIRE  
These are measurement of ${\mathit m}_{{{\mathit \nu}}}$ (in contrast to ${\mathit m}_{{{\overline{\mathit \nu}}}}$, given above). The masses can be different for a Dirac neutrino in the absence of $\mathit CPT$ invariance. The possible distinction between ${{\mathit \nu}}$ and ${{\overline{\mathit \nu}}}$ properties is usually ignored elsewhere in these Listings.
