A comparative study on B > K*l(+)l() and B > K0*(1430)l(+)l() decays in the supersymmetric models
Bashiry, Vali; Bayar, Melahat; Azizi, Kazem (World Scientific Publishing, 20110420)In this paper, we compare the branching ratio and rate difference of electron channel to muon channel of B > K0*(1430)l(+)l() and B > K*l(+)l() decays, where K0*(1430) is the pwave scalar meson, in the supersymmetric ... 
FCNC transitions of Lambda(b,c) to nucleon in SM
Azizi, Kazem; Bayar, Melahat; Saraç, Yasemin; Sundu, Hayriye (IOP Publishing, 201011)We provide a comprehensive study of semileptonic flavorchanging neutral current transitions for Lambda(b) > nl(+) l() and Lambda(c) > pl(+) l() in the context of light cone QCD sum rules. Using the most general form ... 
Flavorchanging neutral currents transition of the Sigma(Q) to nucleon in full QCD and heavy quark effective theory
Azizi, Kazem; Bayar, Melahat; Zeyrek, Mehmet T. (IOP Publishing, 201008)The looplevel flavorchanging 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. ... 
G(Sigma Q Sigma Q pi) coupling constant via light cone QCD sum rules
Azizi, Kazem; Bayar, Melahat; Özpineci, Altuğ; Saraç, Yasemin (American Physical Society, 20101011)Using the most general form of the interpolating currents, the coupling constants g(Sigma b Sigma b pi) and g(Sigma c Sigma c pi) are calculated within the light cone QCD sum rules approach. It is found that g(Sigma c Sigma ... 
Scalar quarkonia at finite temperature
Veliev, Elşen Veli; Sundu, Hayriye; Azizi, Kazem; Bayar, Melahat (American Physical Society, 20100928)Masses and decay constants of the scalar quarkonia, chi(Q0)(Q = b, c) with quantum numbers IG (J(PC)) = 0(+)(0(++)), are calculated in the framework of the QCD sum rules approach both in vacuum and finite temperature. The ... 
Semileptonic Lambda b,c to nucleon transitions in full QCD at light cone
Azizi, Kazem; Bayar, Melahat; Saraç, Yasemin; Sundu, Hayriye (American Physical Society, 200911)The treelevel semileptonic Lambda(b)> pl nu and Lambda(c)> nl nu transitions are investigated using the light cone QCD sum rules approach in full theory. The spin 1/2, Lambda(Q) baryon with Q=b or c, is considered by ... 
Semileptonic transition of Sigma(b) to Sigma in light cone QCD sum rules
Azizi, Kazem; Bayar, Melahat; Özpineci, Altuğ; Saraç, Yasemin; Sundu, Hayriye (American Physical Society, 20120103)We use distribution amplitudes of the light Sigma baryon and the most general form of the interpolating current for heavy Sigma(b) baryon to investigate the semileptonic Sigma(b) > Sigma l(+)l() transition in light cone ...
