Efektif U(1)' Modellerinde Doğallığın İncelenmesi

Öz

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.

Investigation of Naturalness in Effective U(1)' Models

Öz

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.
