Analysis of the radiative Lambda(b) -> Lambda(gamma) transition in the standard model and scenarios with one or two universal extra dimensions
Azizi, Kazem; Kartal, Sehban; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (American Physical Society, 2013-07-26)We investigate the radiative process of Lambda(b) -> Lambda(gamma) in the standard model as well as models with one or two compact universal extra dimensions. Using the form factors entered to the low-energy matrix elements, ... -
Analysis of the semileptonic Lambda(b) -> Lambda l(+)l(-) transition in the topcolor-assisted technicolor model
Azizi, Kazem; Kartal, Sehban; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (American Physical Society, 2013-10-15)We comparatively analyze the flavor-changing neutral current process of Lambda(b) -> Lambda l(+)l(-) in the standard model as well as the topcolor-assisted technicolor model using the form factors calculated via light cone ... -
Comparative analysis of the semileptonic Lambda(b) -> Lambda l(+)l(-) transition in SM and different SUSY scenarios using form factors from full QCD
Azizi, Kazem; Kartal, Sehban; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (Springer Verlag, 2012-10)We work out the semileptonic Lambda(b) -> Lambda l(+)l(-) transition in standard as well as different supersymmetric models. In particular, considering the parametrization of the matrix elements entered the low energy ... -
Comparative analysis of the Λb → Λℓ+ℓ- decay in the SM, SUSY, and RS model with custodial protection
Azizi, Kazem; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (American Physical Society, 2015-12-30)We comparatively analyze the rare Λb→Λℓ+ℓ- channel in the standard model, supersymmetry, and Randall-Sundrum model with custodial protection (RSc). Using the parametrization of the matrix elements entering the low-energy ... -
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 ... -
Impact of scalar leptoquarks on heavy baryonic decays
Azizi, Kazem; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (Hindawi, 2017)We present a study on the impact of scalar leptoquarks on the semileptonic decays of Lambda(b) , Sigma(b) , and Xi(b) . To this end, we calculate the differential branching ratio and lepton forward-backward asymmetry ... -
Radiative Σb→Σγ decay in SM and BSM
Azizi, Kazem; Kartal, Sehban; Olgun, Asiye Tuğba; Tavukoğlu, Zeynep (IOP Publishing, 2014-09)Using transition form factors calculated via light cone QCD sum rules in full theory, we comparatively analyze the rare radiative Sigma(b) -> Sigma gamma decay in the standard model (SM) and models with one or two universal ...
