We proposed a supersymmetric extension of Modified Mirror Model in order to avoid hierarchy problem. Different from Minimal Supersymmetric Standard Model (MSSM), Supersymmetric Modified Mirror Model does not contain the two Higgs superfields ( ˆHu dan ˆHd). Instead, we use the first generation of the neutrino superpartners (sneutrino) in order to generate particles mass. This model uses Rsymmetry instead of R-parity in order to avoid superpotential that violates lepton and baryon number. In this model, we find a new contribution in pion decay into antineutrino and lepton with leptoquark, which is the up quark superpartner, as propagator. The leptoquark lower bound mass is 1.15 Tev.
