The loop level flavor changing neutral current transitions of the Sigma(b) -> nl(+)l(-) and Sigma(c) -> p l(+)l(-) are investigated in full QCD and heavy quark effective theory in the light cone QCD sum rules approach. Using the most general form of the interpolating current for E-Q, Q = b or c, the transition form factors are calculated using two sets of input parameters entering the nucleon distribution amplitudes. The obtained results are used to estimate the decay rates of the corresponding transitions.

Sigma(b,c) to Nucleon Transitions in Light Cone QCD Sum Rules BAYAR, MELAHAT; AZİZİ, KAZEM; Zeyrek, Mehmet Tevfik (2010-09-03) The loop level flavor changing neutral current transitions of the Sigma(b) -> nl(+)l(-) and Sigma(c) -> pl(+)l(-) are investigated in the light cone QCD sum rules approach. Using the most general form of the interpolating current for Sigma(Q), Q - b or c, the transition form factors are calculated using two sets of input parameters entering the nucleon distribution amplitudes, namely, QCD sum rules and lattice QCD inputs. The obtained results are used to estimate the decay rates of the corresponding transit...
Optical characterization of silicon based hydrogenated amorphous thin films by un-visible and infrared measurements Kılıç, İlker; Katırcıoğlu, Bayram; Department of Physics (2006) Various carbon content hydrogenated amorphous silicon carbide (a-Si1ŁxCx:H) and hydrogenated amorphous silicon (a-Si:H) thin films have been deposited on various substrates by using plasma enhanced chemical vapour deposition (PECVD) technique. Transmission spectra of these films have been determined within UV-Visible region and the obtained data were analysed to find related physical constants such as; refractive indices, thicknesses, etc. Fourier transform infrared (FT-IR) spectrometry technique has been u...
Flavor-changing neutral currents transition of the Sigma(Q) to nucleon in full QCD and heavy quark effective theory AZİZİ, KAZEM; BAYAR, MELAHAT; Zeyrek, Mehmet Tevfik (IOP Publishing, 2010-08-01) The loop-level flavor-changing neutral currents transitions of the Sigma(b) -> nl(+)l(-) and Sigma(c) -> pl(+)l(-) are investigated in full QCD and heavy quark effective theory in the light cone QCD sum rules approach. Using the most general form of the interpolating current for Sigma(Q), Q = b or c, as members of the recently discovered sextet heavy baryons with spin 1/2 and containing one heavy quark, the transition form factors are calculated using two sets of input parameters entering the nucleon distri...
Nuclear emulsions in a large, hybrid experiment (CHORUS) to search for nu(mu) -> nu(tau) oscillations Aoki, S; et. al. (2000-06-11) We describe the (2 x 800 kg) emulsion target in the CHORUS hybrid detector set-up for the search of nu(mu) --> nu(tau) oscillations. together with the CERN pouring and processing facilities (upgraded for this purpose), and the techniques employed to treat the emulsions used as the active target in the experiment.
Conformal black hole solutions of axidilaton gravity in D dimensions Cebeci, H; Dereli, T (2002-02-15) Static, spherically symmetric solutions of axidilaton gravity in D dimensions are given in the Brans-Dicke frame for arbitrary values of the Brans-Dicke constant omega and an axion-dilaton coupling parameter k. The mass and the dilaton and axion charges are determined and a BPS bound is derived. There exists a one-parameter family of black hole solutions in the scale-invariant limit.
