A review of neutrino properties: Neutrino oscillations - a historical overview and its projection

In a first part neutrino properties are presented from the beginnings through the letter of Wolfgang Pauli on 4. December 1930 suggesting a new neutral fermion to the “Radioactive Ladies and Gentlemen” at a Conference in Tübingen, contributing to the first oscillation cycle, based on my review at the meeting “Neutrino Telescopes in Venice” in 2005. cited in [1]. In the remaining part I shall present a selection of neutrino properties featuring the structure of mass and mixing of the light and heavy neutrino flavors, a symmetric, complex 6 by 6 matrix within the unifying SO10 gauge group, and present prospects for the detection of the leptonflavor violating processes $B_s \rightarrow\mu \ e$; $B \rightarrow K \ \mu \ e$, also such involving b-flavored baryons .
