Neutrinos are remarkable
particles - their interactions show many regularities and a few surprises, like the mixing among neutrinos of different families (generations). In order to understand the origin of mixing and determine the parameters precisely, we need to understand
(1) the nature of neutrinos: are they Dirac or Majorana particles, and
(2) Precise values for their interactions with hadrons. Many of the interactions will be measured again in the new
generation of experiments including long base line
experiments.
The seminar will cover several of the above topics and will point out the progress that has been made. In addition, Majorana neutrinoscan produce, in the early universe, a lepton-asymmetry which was
converted later on to a
baryon-asymmetry that we observe today. The possible connection of this phenopmenon to the laboratory experiments
will be discussed.
