DESCRIPTION:In this seminar I will analyze the nuclear structure aspects o
 f the 0nu double beta decay nuclear matrix elements (NME) in the framework
  of the Interacting Shell Model. I will present results for the decays of 
 48Ca\, 76Ge\, 124Sn\, 128Te\, 130Te\, and 136Xe\, using improved effective
  interactions and valence spaces. �I will submit that the �NME's are e
 xtremely sensitive to the structure of the wave functions in terms of pair
 s of nucleons coupled to angular momentum zero. This point of view gives b
 ack the due protagonism in this process to the pairinginteraction\, the in
 teraction which is responsible for the very existence of double beta decay
  emitters. �I will argue that low seniority approximations\, such as the
  Quasiparticle RPA in an spherical basis\, tend to overestimate the values
  of the NME's.\n\nWARNING: This seminar will be held in the IFIC sala de r
 eunions\, LAB hall (La Trobada room)\, at 10:45.\n\nhttps://indico.ific.uv
