Using the most general, model-independent form of effective Hamiltonian, the exclusive, rare B --> K*v (v) over bar decay is analyzed. The sensitivity of the branching ratio and missing mass-squared spectrum of the B --> K*v (v) over bar decay, when K* is polarized longitudinally or transversally, on the new Wilson coefficients is discussed.

Rare B-s ->gamma nu(nu)over-bar decay with polarized photon and new physics effects Sirvanli, B; Turan, Gürsevil (World Scientific Pub Co Pte Lt, 2003-01-10) Using the most general, model-independent effective Hamiltonian, the rare B-s --> gammanu(ν) over bar decay with polarized photon is studied. The sensitivity of the branching ratio and photon polarization to the new Wilson coefficients are investigated. It is shown that these physical observables are sensitive to the vector and tensor type interactions, which would be useful in search of new physics.
Rare B -> l(+)l(-)gamma decay and new physics effects Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-11-08) Using the most general, model independent form of the effective Hamiltonian rare decays B --> l(+)l(-)gamma (l = mu, tau) are studied. The sensitivity of the photon energy distribution and branching ratio to the new Wilson coefficients is investigated.
Exclusive B -> Ml(+)l(-) (M = pi, K, rho, K*) decays and determinations of vertical bar V-ts vertical bar (and vertical bar V-td/V-ts vertical bar) Alıyev, Tahmasıb; Savci, M (Elsevier BV, 1998-11-26) We examine the possibility for precise determination of /V-ts/ (and /V-td/V-ts/) from the exclusive decays, B --> Kl(+)l(-), B --> K*l(+)l(-) (and B --> pi l(+)l(-), B --> rho l(+)l(-)). We show that the ratio /V-ts/ can be extracted experimentally with a small theoretical uncertainty from hadronic form-factors, if we appropriately constrain kinematical regions of q(2). We also give detailed analytical and numerical results on the differential decay width d Gamma(B --> K*l(+)l(-))/dq(2), and the ratios of i...
Exclusive B -> K*l(+)l(-) decay with polarized K* and new physics effects Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-06-28) Using the most general, model independent effective Hamiltonian, the branching ratio of the B --> K* l(+)l(-) decay, when K* meson is longitudinally or transversally polarized, is presented. The dependence of the branching ratio on the new Wilson coefficients, when K* meson is polarized. is studied. It is observed that the branching ratio is very sensitive to the vector and tenser type interactions, which will be useful in search of new physics beyond the Standard Model.
Double-lepton polarization asymmetries in the B -> Kl(+)l(-) decay beyond the standard model Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2004-06-01) General expressions for the double-lepton polarizations in the B --> Kl(+)l(-)decay are obtained, using a model independent effective Hamiltonian, including all possible interactions. Correlations between the averaged double-lepton polarization asymmetries and the branching ratio, as well as the averaged single-lepton polarization asymmetry are studied. It is observed that a study of the double-lepton polarization asymmetries can serve as a good test for establishing new physics beyond the standard model.
