Analyses of gD*sDK and gB*sBK vertices in QCD sum rules
Süngü, Jale Yılmazkaya; Sundu, Hayriye; Azizi, Kazem (IOP Publishing, 2012)The coupling constants g D*sDK and g B*sBK are calculated in the framework of QCD sum rules. We evaluate the correlation functions of these vertices considering both D(B) and K mesons off-shell and obtain the results as g ... -
Analysis of Ds*DK1 (Bs*BK1) coupling constants within QCD sum rules
Yinelek, Neşe; Süngü, Jale Yılmazkaya; Sundu, Hayriye; Azizi, Kazem (IOP Publishing, 2012)We compute the strong coupling constants for D*sDK1 and B*sBK1 vertices within the QCD sum rules. The coupling constants are calculated for both D(B) and K1 off-shell mesons. -
Properties of Ds2*(2573) charmed-strange tensor meson
Azizi, Kazem; Sundu, Hayriye; Süngü, Jale Yılmazkaya; Yinelek, Neşe (American Physical Society, 2013-08-19)The mass and current coupling constant of the D-s2*(2573) charmed-strange meson is calculated in the framework of the two-point QCD sum rule approach. Although the quantum numbers of this meson are not exactly known, its ... -
Semileptonic Lambda(b) -> Lambda(c)l(v)over-bar(l) transition in full QCD
Azizi, Kazem; Süngü, Jale Yılmazkaya (American Physical Society, 2018-04)The tree-level b -> cl (v) over bar (l) based hadronic transitions have been the focus of much attention since recording significant deviations of the experimental data, on the ratios of the branching fractions in tau and ... -
Semileptonic transition of P-wave bottomonium chi(b0)(1P) to B-c meson
Azizi, Kazem; Sundu, Hayriye; Süngü, Jale Yılmazkaya (Springer, 2012-08-14)Taking into account the two-gluon condensate contributions, the transition form factors enrolled to the low-energy effective Hamiltonian describing the semileptonic chi(b0) -> B(c)l (nu) over bar, (l = (e, mu, tau)) decay ... -
Semileptonic transition of tensor chi(c2)(1P) to D-S meson
Süngü, Jale Yılmazkaya; Sundu, Hayriye; Azizi, Kazem (Hindawi Publishing Corporation, 2014)Taking into account the two-gluon condensate corrections, the transition form factors of the semileptonic chi(c2) -> D-s(l) over bar nu(l - e, mu) decay channel are calculated via three-point QCD sum rules. These form ... -
Strong coupling constants of bottom and charmed mesons with scalar, pseudoscalar, and axial vector kaons
Sundu, Hayriye; Süngü, Jale Yılmazkaya; Şahin, Sinem; Yinelek, Neşe; Azizi, Kazem (American Physical Society, 2011-06-02)The strong coupling constants, gD(s)DK(0)*, gB(s)BK(0)*, gD(s)*DK, gB(s)*BK, gD(s)*DK1 and gB(s)*BK(1), where K(0)*, K and K(1) are scalar, pseudoscalar, and axial-vector kaon mesons, respectively, are calculated in the ... -
Transition form factors of chi(b2)(1P) -> B-c(l)over-barv in QCD
Azizi, Kazem; Sundu, Hayriye; Süngü, Jale Yılmazkaya; Yinelek, Neşe (Hindawi, 2016)The form factors of the semileptonic chi(b2)(1P) -> B-c(l) over barv decay are calculated by using the QCD sum rule technique. The results obtained are then used to estimate the decay widths of this transition in all lepton ...
