We study the polarized lepton pair forward-backward asymmetries in B --> K*l+l(-) decay using a general, model independent form of the effective hamiltonian. We present the general expression for nine double-polarization forward-backward asymmetries. It is shown that, the study of the forward-backward asymmetries of the doubly-polarized lepton pair is a very useful tool for establishing new physics beyond the standard model.

Double-lepton polarizations in B -> l(+)l(-)gamma decay Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2005-02-01) Double-lepton polarization asymmetries in the B-->l(+)l(-)gamma decay are calculated using the most general, model independent form of the effective Hamiltonian including all possible forms of the interaction. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability of the averaged double-lepton polarization asymmetries at LHC is also discussed.
Exclusive B ->rho l(+)l(-) decay and polarized lepton pair forward-backward asymmetries Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2006-02-01) The polarized lepton pair forward-backward asymmetries in B ->rho l(+)l(-) decay using a general, model independent form of the four-Fermi interaction is studied. The general expressions for nine double-lepton polarization forward-backward asymmetries are calculated. The study of the forward-backward asymmetries of the doubly polarized lepton pair proves to be a very useful tool in looking for new physics beyond the standard model.
Nucleon electromagnetic form factors in QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 2008-06-01) The nucleon electromagnetic form factors are calculated in a light cone QCD sum rules framework using the most general form of the nucleon interpolating current. Using two models for the distribution amplitudes, we predict the form factors. The predictions are also compared with existing experimental data. It is shown that our results describe remarkably well the existing experimental data.
Sigma(Q)Lambda(Q)pi coupling constant in light cone QCD sum rules Azizi, K.; Bayar, M.; Özpineci, Altuğ (American Physical Society (APS), 2009-03-01) The strong coupling constants g(Sigma Q)Lambda(Q)pi (Q=b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the Sigma(Q)->Lambda(Q)pi decays which are compared with the predictions of the other approaches and existing experimental data.
Heavy baryon-light vector meson couplings in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-02-15) The strong coupling constants of heavy baryons with light vector mesons are calculated in the framework of the light cone QCD sum rules using the most general form of the interpolating currents for the heavy baryons. It is shown that the sextet sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one invariant function for each class of transitions. The values of the electric and magnetic coupling constants for these transitions are obtained.
