Dark matter from conformal sectors
Demir, Durmuş Ali; Frank, Mariana; Korutlu, Beste (Elsevier, 2014)We show that a conformal-invariant dark sector, interacting conformally with the Standard Model (SM) fields through the Higgs portal, provides a viable framework where cold dark matter (CDM) and invisible Higgs decays can ... -
Doubly charged Higgsinos at LHC
Demir, Durmuş Ali; Frank, Mariana; Huitu, Katri; Rai, Santosh Kumar; Turan, İsmail (Proceedings of Science, 2008)We review single and pair production and subsequent decay of doubly charged Higgsinos of the left-right supersymmetric model at the LHC. The novel signature is possible to separate from the MSSM and UED signal. -
Doubly charged Higgsinos at the Tevatron
Demir, Durmuş Ali; Frank, Mariana; Ghosh, Dilip Kumar; Huitu, Katri; Rai, Santosh Kumar; Turan, İsmail (American Physical Society, 2009-05)Several supersymmetric models with extended gauge structures, motivated by either grand unification or by neutrino mass generation, predict light doubly charged Higgsinos. In this work we study the signals of doubly charged ... -
Neutralino dark matter in the left-right supersymmetric model
Demir, Durmuş Ali; Frank, Mariana; Turan, İsmail (American Physical Society, 2006)We study the neutralino sector of the left-right supersymmetric model. In addition to the possibilities available in the minimal supersymmetric model, the neutralino states can be superpartners of the U(1)B-L gauge boson, ... -
Search for gauge extensions of the MSSM at the LHC
Ahmed, Ali; Demir, Durmuş Ali; Frank, Mariana; Turan, İsmail (American Physical Society, 2009-05)The extensions of the minimal supersymmetric model (MSSM), driving mainly from the need to solve the μ problem, involve novel matter species and gauge groups. These extended MSSM models can be searched for at the LHC via ... -
Signals of doubly-charged Higgsinos at the CERN Large Hadron Collider
Demir, Durmuş Ali; Frank, Mariana; Huitu, Katri; Rai, Santosh Kumar; Turan, İsmail (American Physical Society, 2008-08-28)Several supersymmetric models with extended gauge structures, motivated by either grand unification or by neutrino mass generation, predict light doubly-charged Higgsinos. In this work we study productions and decays of ... -
Signatures of doubly-charged Higgsinos at colliders
Demir, Durmuş Ali; Frank, Mariana; Huitu, Katri; Rai, Santosh Kumar; Turan, İsmail (American Institute of Physics Publising, 2008)Several supersymmetric models with extended gauge structures predict light doubly-charged Higgsinos. Their distinctive signature at the large hadron collider is highlighted by studying its production and decay characteristics. -
Sneutrino dark matter: Symmetry protection and cosmic ray anomalies
Demir, Durmuş Ali; Everett, Lisa L.; Frank, Mariana; Selbuz, Levent; Turan, İsmail (American Physical Society, 2010-02)We present an R-parity conserving model of sneutrino dark matter within a Higgsphilic U(1)′ extension of the minimal supersymmetric standard model. In this theory, the μ parameter and light Dirac neutrino masses are generated ...
