SUMMARY:Neutrinoless double beta decay in effective field theory\, Net
 work in Neutrinos\, Nuclear Astrophysics\, and Symmetries (N3AS) Semin
 ar\, Wouter Dekens\, UCSD
DESCRIPTION:Neutrinoless double beta decay (NLDBD) is the most sensiti
 ve probe of lepton-number violation. Its discovery would be a clear si
 gnal of physics beyond the Standard Model\, confirm the Majorana natur
 e of neutrinos\, and provide insight into scenarios of baryogenesis th
 rough leptogenesis. Whenever lepton-number violation arises at a scale
  well above the electroweak scale\, it can be described by effective i
 nteractions in an effective-field theory framework. In this talk\, I w
 ill outline the steps necessary to assess the impact of these interact
 ions on NLDBD half lives\, paying special attention to the matching of
  the effective interactions onto Chiral Effective Theory at low energi
 es. In addition\, I will discuss how this framework can be extended to
  include the effects of light sterile neutrinos and give an overview o
 f the resulting constraints on the lepton-number violating interaction
 s.
