Rare decay of the top quark t -> cl(l)over-bar and single top quark production at the ILC
Frank, Mariana; Turan, İsmail (American Physical Society (APS), 2006-10-01)
We perform a complete and detailed analysis of the flavor changing neutral current rare top quark decays t -> cl(+)l(-) and t -> c nu(i)(nu) over bar (i) at one-loop level in the standard model, two Higgs doublet models (I and II), and in minimal supersymmetric standard model (MSSM). The branching ratios are very small in all models, O(10(-14)), except for the case of the unconstrained MSSM, where they can reach O(10(-6)) for e(+)e(-), mu(+)mu(-), and nu i (nu) over bari, and O(10(-5)) for tau(+)tau(-).

Rare B->K*l(+)l(-) decay, two Higgs doublet model, and light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (1997-10-02)
The decay width, forward-backward asymmetry and lepton longitudinal and transversal polarization for the exclusive B --> K* l(+)l(-) decay in a two Higgs doublet model are computed. It is shown that all these quantities are very effective tools for establishing new physics. (C) 1997 Elsevier Science B.V.
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.
RARE DECAY B-]K-STAR-GAMMA IN STANDARD AND SUPERSYMMETRIC MODELS
Alıyev, Tahmasıb; SLOBODENYUK, VA (1990-03-22)
The formfactor of the rare decay is calculated with the help of the QCD sum rule method for the three-point correlators. Using this formfactor we found that when the sensitivity of the measurements is raised 3–4 times, one could either obtain an upper limit on mt, or detect the decay considered.
