Since 2011 the GERmanium Detector Array (Gerda) experiment has collected data at the Gran Sasso Laboratory (Italy). Recently the experiment released the results of their search for neutrinoless double beta decay of the isotope 76Ge. Neutrinoless double beta decay is a process that violates lepton number conservation, but is predicted to occur in extensions of the Standard Model of particle physics. No signal was observed and a lower limit of 2.1x10^25 yr (90% C.L) was derived for the half-life of this decay. In this talk the Gerda experiment will be described, the results explained and its effects on the effective neutrino mass and on physics beyond the standard model investigated.
