Analysis of the Lambda(b) -> Lambda l(+)l(-) transition in the SM4 using form factors from full QCD
Azizi, Kazem; Katırcı, Nihan (Springer, 2012-05-25)Using the responsible form factors calculated via full QCD, we analyze the Lambda(b) -> Lambda l(+)l(-) transition in the standard model containing fourth-generation quarks (SM4). We discuss the effects of the presence of ... -
B to strange tensor meson transition in a model with one universal extra dimension
Katırcı, Nihan; Azizi, Kazem (Springer Verlag, 2011-07-08)We analyze the semileptonic B -> K-2* (1430)l(+)l(-) transition in universal extra dimension model. In particular, we present the sensitivity of related observables such as branching ratio, polarization distribution and ... -
Constraint on compactification scale via recently observed baryonic nu(b) -> nu l(+)l(-) channel and analysis of the Sigma(b) -> Sigma l(+)l(-) transition in SM and UED scenario
Azizi, Kazem; Kartal, Sehban; Katırcı, Nihan; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (Springer Verlag, 2012-05)We obtain a lower limit on the compactification scale of extra dimension via comparison of the branching ratio in the baryonic A(b) -> A mu(+)mu(-) decay channel recently measured by CDF collaboration and our previous ... -
A cosmological exact solution of generalized Brans - Dicke theory with complex scalar field and its phenomenological implications
Arık, Metin; Çalık, Mehmet; Katırcı, Nihan (Springer, 2011-12)When the Brans-Dicke theory is formulated in terms of the Jordan scalar field phi, the amount of dark energy is related to the mass of this field. We investigate a solution which is relevant to the late universe. We show ... -
Investigation of the Lambda(b) -> Lambda l(+)l(-) transition in universal extra dimension using form factors from full QCD
Azizi, Kazem; Katırcı, Nihan (Springer, 2011-01)Using the related form factors from full QCD which recently are available, we provide a comprehensive analysis of the Lambda b -> Lambda l(+)l(-) transition in universal extra dimension model in the presence of a single ... -
QCD nature of dark energy at finite temperature: Cosmological implications
Azizi, Kazem; Katırcı, Nihan (Springer Berlin Heidelberg, 2016-05)The Veneziano ghost field has been proposed as an alternative source of dark energy, whose energy density is consistent with the cosmological observations. In this model, the energy density of the QCD ghost field is expressed ... -
Semileptonic transition of Sigma(b) -> Sigma mu(+)mu(-) in the family non-universal Z ' model
Katırcı, Nihan; Azizi, Kazem (IOP Publishing, 2013-08)Using newly available form factors obtained from light-cone QCD sum rules in full theory, we study the flavor-changing neutral current transition of Sigma(b) -> Sigma mu(+)mu(-) decay in the family non-universal Z' model. ...
