    Higgs Boson Masses in the Mssm With General Soft Breaking
    (Elsevier Ltd., 2008) Sabancı, Aslı; Hayreter, Alper; Solmaz, Levent
    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 singlets. In minimal supersymmetric model (MSSM) we discuss the impact of non-holomorphic soft-breaking terms on the Higgs sector. We find that non-holomorphic operators can cause significant changes as are best exhibited by the correlation between the masses of the charginos and Higgs bosons

    Dilepton Signatures of Family Non-Universal U (1)'
    (Elsevier Ltd., 2007) Hayreter, Alper
    The supersymmetric models extending the minimal supersymmetric Standard Model (MSSM) by an additional Abelian gauge factor U (1)′ in order to solve the μ problem do generically suffer from anomalies disrupting the gauge coupling unification found in the MSSM. The anomalies are absent if the minimal matter content necessitated by the μ problem is augmented with exotic matter species having appropriate quantum numbers. Recently, it has been shown that anomaly cancellation can also be accomplished by introducing family non-universal U (1)′ charges and non-holomorphic soft-breaking terms [D.A. Demir, G.L. Kane, T.T. Wang, Phys. Rev. D 72 (2005) 015012, hep-ph/0503290]. We discuss collider signatures of anomaly-free family non-universal U (1)′ model by analyzing dilepton production in future colliders. We find that, both at LHC and NLC, one can establish existence/absence of such a Z′ boson by simply comparing the number of dilepton production events for electron, muon and tau lepton. The signal is free of the SM background.

    Electric Dipole Moments in U(1)' Models
    (American Physical Society, 2008) Hayreter, Alper; Sabancı, Aslı; Solmaz, Levent; Solmaz, Saime
    We study electric dipole moments of electrons and protons in E(6)-inspired supersymmetric models with an extra U(1) invariance. Compared to the Minimal Supersymmetric Standard Model, in addition to offering a natural solution to the μ problem and predicting a larger mass for the lightest Higgs boson, these models are found to yield suppressed electric dipole moments. © 2008 The American Physical Society.
