Bu çalışmada Büyük Hadron Çarpıştırıcısı (BHÇ) ve karanlık madde sonuçları çerçevesinde, son deneysel veriler kullanılarak sınırlandırılmış Minimal Süpersimetrik Standart Model (CMSSM)'in durumu incelenmiş ve parametre uzayına ilişkin sınırlamalar gözlemlenerek gelecekteki deneyler için öngörülerde bulunulmuştur.

Anahtar Kelimeler

CMSSM in the light of the recent experimental data

Öz

In this study, we probe the status of CMSSM under the recent experimental data from the LHC and Dark Matter results. We also restrict the parameter space and make predictions for the future experiments.

Anahtar Kelimeler

Supersymmetry, CMSSM, Large Hadron Collider.
