  We examine the pion realization of the short ranged supersymmetric (SUSY)
mechanism of neutrinoless double beta decay. It originates from the R-parity
violating quark-lepton interactions of the SUSY extensions of the standard
model of the electroweak interactions. We argue that pions are dominant SUSY
mediators in neutrinoless double beta decay. The corresponding nuclear matrix
elements for various isotopes are calculated within the proton-neutron
renormalized quasiparticle random phase approximation. We define those isotopes
which are most sensitive to the SUSY signal and outlook the present
experimental situation with the double beta decay searches for the SUSY. Upper
limits on the R-parity violating 1st generation Yukawa coupling are derived
from various double beta decay experiments.
