Cern lep indications for two light higgs bosons and the u(1)' model
Demir, Durmuş; Solmaz, Levent; Solmaz, Saime (Amer Physical Soc, 2006)Reanalyses of LEP data have shown preference to two light CP-even Higgs bosons. We discuss implications of such a Higgs boson spectrum for the minimal supersymmetric model extended by a standard model singlet chiral ... -
Efektif U(1)' modellerinde doğallığın incelenmesi
Hiçyılmaz, Yaşar (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2012)U(1)' modeli standart model sonrası süpersimetrik modellerin en etkililerinden biridir. Bu modele göre doğada ekstra bir elektro-zayıf ayar simetrisi vardır. Bundan dolayı bu modelin parçacık spektrumunda MSSM'e ek olarak ... -

Generalized soft breaking leverage for the MSSM
Un, Cem Salih; Tanyıldızı, Şükrü Hanif; Kerman, Saime; Solmaz, Levent (Amer Physical Soc, 2015)In this work we study implications of additional nonholomorphic soft breaking terms (mu', A(t)', A(b)', and A(t)') on the minimal supersymmetric extension of the standard model (MSSM) phenomenology. By respecting the ... -
Higgs boson masses in the MSSM with general soft breaking
Sabancı, Aslı; Hayreter, Alper; Solmaz, Levent (2008)The operators that break supersymmetry can be holomorphic or non-holomorphic in structure. The latter do not pose any problem for gauge hierarchy and are soft provided that the particle spectrum does not contain any gauge ... -

Frank, Mariana; Selbuz, Levent; Solmaz, Levent; Turan, İsmail (American Physical Society, 2013)We study the Higgs sector of the U(1)'-extended minimal supersymmetric standard model with CP violation. This is an extension of the minimal supersymmetric standard model Higgs sector by one singlet field, introduced to ... -

Kozmik enflasyon modellemeleri
Özdilek, Şule (Balıkesir Üniversitesi Fen Bilimleri Enstitüsü, 2016)Evrenin erken dönemlerine açıklık getirmek üzere en kabul görmüş teori kozmik enflasyondur. Enflasyon teorisine göre evren üstel olarak çok hızlı bir şekilde genişlemiştir. Bu teori Büyük Patlamanın sorunlarına çözüm ... -
Least fine-tuned U(1) extended SSM
Hiçyılmaz, Yaşar; Solmaz, Levent; Tanyıldızı, Şükrü Hanif (Elsevier Science, 2018)We consider the Higgs boson mass in a class of the UMSSM models in which the MSSM gauge group is extended by an additional U(1)' group.

Model characterization and dark matter in the secluded U(1)' model
Hiçyılmaz, Yaşar; Selbuz, Levent; Solmaz, Levent; Un, Cem Salih (Amer Physical Soc, 2022)We consider a class of U(1)'-extended minimal supersymmetric extension of the Standard Model (MSSM) in which the U(1)' symmetry is broken by vacuum expectation values of four MSSM singlet fields. While one MSSM singlet ... -
