Bu çalıșmada Süpersimetrik U(1)’ Modeller'inde parçacık kütlelerinin deneylerle uyumlu bölgeleri belirlenmiștir. Bu yapılırken, renormalizasyon grup eșitlikleri ile Büyük Birleșim Teorisi (BBT) skalasından zayıf skalaya getirilen
At , Ab , As, ht, hb, hs.... vb. parametreler kullanılmıștır. Ardından, bu izin verilen
bölgeler için ince-ayar hesaplanmıștır. Tüm hesaplamalarda eldeki deneysel veriler göz
önüne alınmıștır. Sonuç olarak, en düșük ince ayara sahip (en doğal) parametre
uzaylarının belirttiği en hafif Higgs kütlesi hesaplanmıștır.

In this study, regions compatible with experiments of the particle masses m%, m%, mt%, m%, m′b% Z′ are determined for Supersymmetric U(1)' Models. While doing this, it is used the parameters, At , Ab , As, ht, hb, hs.... etc. brought from Grand Unification Theory
(GUT) scale to the weak scale by renormalization group equations. Then, fine-tuning
for the allowed regions is calculated. As a result, the lightest Higgs mass, noted
parameter spaces with the lowest fine-tuning (the most natural), is calculated.
