SUMMARY:Neutrinos: The Desperate Remedy - Hirohisa Tanaka (University of To
 ronto)
DESCRIPTION:Neutrinos: The Desperate Remedy - Hirohisa Tanaka (University o
 f Toronto)
\n 
\nIf something can’t be detected\, can we actually say i
 t exists? This was the conundrum facing Wolfgang Pauli when he proposed th
 at a neutral particle (i.e. the neutrino) is emitted in the beta decay of 
 a nucleus. While it solved some profound mysteries\, it was soon suggested
  that such a particle would be impossible to detect. Nearly a century late
 r\, we not only have detected neutrinos\, but understand that they come in
  three species\, have antimatter counterparts\, and that they play a cruci
 al role as fundamental building blocks of the Universe and in determining 
 its structure. I will discuss how neutrino oscillations\, the transmutatio
 n of the neutrino among its three species\, have uncovered some of its fun
 damental properties (such as the fact that it has a tiny but non-zero mass
 ). Befitting its history\, these studies have answered some questions abou
 t neutrinos but the answers are bizarre and raise new questions. In the ne
 ar future\, we hope to understand the relationship between the neutrino an
 d antineutrino\, which may provide critical clues in the continuing parado
 x of how the universe came to be dominated by matter.
\nCette conférence 
 s'adresse à tous\, y compris les professeurs\, les chercheurs et les étu
 diants des trois cycles.
\n Le café est servi à partir de 11h30.
