RADIATIVE D-ASTERISK MESON DECAYS IN QCD SUM-RULES Alıyev, Tahmasıb; PAK, NK (1994-08-11) The radiative decays D(a)* - D(a)gamma is investigated in the framework of QCD sum rules. The transition amplitude and decay rates are estimated. It is shown that our results on branching ratios are in good agreement with the existing experimental data.
Exclusive radiative weak decays of B-c meson in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa (1998-12-01) We investigate the radiative B-c --> p(+)gamma and B-c --> K*(+gamma) decays in the standard model. The transition form factors are calculated in the framework of the light cone QCD sum rules method. We estimate the branching ratios of the B-c --> p(+)gamma and B-c --> K*(+)gamma decays.
Semileptonic B ->eta iota nu decay in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ (American Physical Society (APS), 2003-05-01) We study the semileptonic decay B --> eta/nu. The transition form factors for this decay are calculated by using light cone QCD sum rules. The branching ratio is estimated to be B(B --> etanu) = (1.6 +/- 0.8) x 10(-5).
Radiative B-* meson decays in QCD sum rules Alıyev, Tahmasıb; Pak, NK (Springer Science and Business Media LLC, 1997-01-01) The decay constant g(B)* of the B* mesons and the transition amplitudes of the radiative decays B-a* --> B-a gamma are calculated in the frame-work of QCD sum rules. It is shown that the decay rates B* --> B gamma are one order smaller than the corresponding D* meson decays.
Spectroelectrochemical investigation of pentacarbonyl(pyrazine)metal(0) (metal = Cr, Mo, W) complexes of group 6 elements Yaman, SO; Nalbant Esentürk, Emren; Kayran, C; Önal, Ahmet Muhtar (2002-01-01) The electrochemical behaviour of pentacarbony l(pyrazine) metal (0) complexes of the group 6 elements was studied by cyclic voltammetry in dichloromethane-(n-Bu)(4)NBF4 solvent-electrolyte couple at -20 degreesC vs. Ag/Ag+ or SCE reference electrode. Constant potential electrolyses of the complexes were carried out at their first oxidation peak potentials and monitored in situ by UV-Vis spectrometry. Electrolysis of W(CO)(5)pz produces [W(CO)(5)pz](+) and a similar electrochemical mechanism is expected both...
