DESCRIPTION:Speakers: Takaharu Otsuka (Department of Physics\, University 
 of Tokyo)\nThe neutrinoless double beta decay is of special importance in 
 determining the fundamental properties of neutrinos. The nuclear matrix el
 ement of this decay must be evaluated in a sufficient accuracy\, and the s
 hell-model calculation can make contributions to this end.  This is becaus
 e the shell-model calculations incorporate basically all correlations into
  the wave functions of the initial and final states of the decay\, and the
  accuracy of the calculation can be investigated by referring to other obs
 ervables.  I will report results obtained by recent large-scale shell-mode
 l calculations on 76Ge and 136Xe as well as their daughter nuclei 76Se and
  136Ba.   Here the large-scale shell-model calculations mean those by Mont
 e Carlo Shell Model at its most advanced edition.  The results are not awa
 y from the ranges of earlier studies\, but are rather on the edges of smal
 ler values.  I will also discuss why such smaller values arise as natural 
 consequences of basic features of the wave functions.\n\nhttps://indico.tl
