We study lepton polarization asymmetries in the Lambda(b)-->Lambdal(+)l(-) decay using the most general model independent effective Hamiltonian. The dependence of the lepton polarizations and their combinations on the new Wilson coefficients are studied in detail. It is observed that there is a region for the new Wilson coefficients for which the branching ratio coincides with the standard model prediction, while lepton polarizations show considerable departure from the standard model.

New physics effects to the lepton polarizations in the B -> Kl(+)l(-) decay
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-09-01)
Using the general, model independent form of the effective Hamiltonian, the general expressions of the longitudinal, normal, and transversal polarization asymmetries for l(-) and l(+) and combinations of them for the exclusive B-->Kl(+)l(-) decay are found. The sensitivity of lepton polarizations and their combinations on new Wilson coefficients are studied. It is found that there exist regions of Wilson coefficients for which the branching ratio coincides with the standard model result while the lepton pol...
The effects of non-universal extra dimensions on the radiative lepton flavor decays mu -> e gamma and tau ->mu gamma in the two Higgs doublet model
Iltan, EO (2004-08-01)
We study the effect of non-universal extra dimensions on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these effects are small for a single extra dimension, however, in the case of two extra dimensions there is a considerable enhancement in the additional contributions.
Double-lepton polarization asymmetries and branching ratio of the B -> gamma l(+)l(-) transition in universal extra dimension
AZİZİ, KAZEM; Pak, N. K.; ŞİRVANLI, BERİN BELMA (2012-02-01)
We study the radiative dileptonic B ->gamma l(+)l(-) transition in the presence of a universal extra dimension in the Applequist-Cheng-Dobrescu model. In particular, using the corresponding form factors calculated via light cone QCD sum rules, we analyze the branching ratio and double lepton polarization asymmetries related to this channel and compare the results with the predictions of the standard model. We show how the results deviate from predictions of the standard model at lower values of the compacti...
New design methods for polyhedral linkages
Kiper, Gökhan; Söylemez, Eres; Department of Mechanical Engineering (2006)
This thesis analyses the existing types of polyhedral linkages and presents new linkage types for resizing polyhedral shapes. First, the transformation characteristics, most specifically, magnification performances of existing polyhedral linkages are given. Then, methods for synthesizing single degree-of-freedom planar polygonal linkages are described. The polygonal linkages synthesized are used as faces of polyhedral linkages. Next, the derivation of some of the existing linkages using the method given is ...
The mu -> e gamma and tau ->mu gamma decays in the general two Higgs doublet model with the inclusion of one universal extra dimension
Iltan, EO (2004-02-01)
We study the effect of one universal extra dimension on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these new effects are tiny for the small values of the compactification radius R. Furthermore, we see that these effects are comparable with the branching ratio obtained without including extra dimension, if the neutral Higgs bosons are nearly degenerate and the complexity of the Yukawa coupling, induci...
