Influence of the fourth generation, if ever exists, on the experimentally measurable quantities such as invariant dilepton mass distribution, lepton forward-backward asymmetry, and the ratio Gamma(L)/Gamma(T) of the decay widths when K* meson is longitudinally and transversally polarized, is studied. Using the experimental results on the branching ratios for the B --> X(s)gamma and semileptonic B --> X(c)l (v) over bar decays, the two possible solutions of the 4 x 4 Cabibbo-Kobayashi-Maskawa factor Vt'sVt'b are obtained as a function of the t'-quark mass. It is observed that the results for the above-mentioned physical quantities are essentially different from the standard model predictions only for one solution of the CKM factor. in this case the above-mentioned physical quantities can serve as efficient tools in search of the fourth generation. The other solution yields almost identical results with the SM.

Tensor form factors of B -> K-1 transition from QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30)
The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Radiative phi -> f(0)(980)gamma decay in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-02-21)
The light cone QCD sum rules method is used to calculate the transition form factor for the radiative phi --> f(0gamma) decay, assuming that the quark content of the f(0) meson is pare (s) over bars state. The branching ratio is estimated to be beta(phi --> f(0)gamma) = 3.5 x (1 +/- 0.3) x 10(-4). A comparison of our prediction on branching ratio with the theoretical results and experimental data existing in literature is presented.
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.
Normalized peak rippple magnitude as an objective function in discrete coefficient fir filter design
Çiloğlu, Tolga (2001-08-17)
Normalized peak ripple magnitude (NPRM) has been a convenient design criterion for discrete coefficient FIR filters. "Filter gain" is the major concern for NPRM. This paper presents an exact closed form expression of the filter gain for a given set of filter coefficients. Based on this expression the characteristics of NPRM cost function are discussed. The selection of the initial value of the filter gain for suboptimal design methods is considered. Deficiency of the previously proposed methods is pointed o...
Interference effects in the decay phi ->pi(0)pi(0)gamma and the coupling constant g(phi sigma gamma)
Gokalp, A; Yılmaz, Osman (2001-09-01)
We study the radiative decay phi --> pi (0)pi (0)gamma within the framework, of a phenomenological approach in which the contributions of sigma mesons, rho mesons, and f(0) mesons are considered. We analyze the interference effects between different contributions and, utilizing the experimental branching ratio for this decay, we estimate the coupling constant g(phi sigma gamma).
