Pada Model Korespondensi Spinor-Skalar diprediksi adanya peluruhan nukleon yang diperantarai oleh leptoquark. Peluruhan nucleon yaitu proton-neutron khusunya proton merupakan salah satu fenomena yang belum dapat dibuktikan secara ekperimen. Tujuan dari penelitian ini untuk mengetahui syarat batas massa leptoquark omega sebagai mediator peluruhan nucleon. Analisa kemungkinan peluruhan dapat diketahui melalui Lagrangan Yukawa, kemudian diplotkan dalam diagram Feynman untuk mengetahui laju peluruhannya dan waktu hidupnya. Batas massa leptoquark omega yang diperoleh berdasarkan variasi terhadap konstanta kopling dan massa neutrino untuk peluruhan proton adalah 23-231 TeV dan 23-73 TeV. Pada Peluruhan neutron, batas massa leptoquark omega terhadap variasi konstanta kopling dan massa neutrino adalah 34-336 TeV dan 34-106 TeV.References
