The coupling constant gρσγ as derived from QCD sum rules
نویسنده
چکیده
We employ QCD sum rules to calculate the coupling constant gρσγ by studying the three point ρσγ-correlation function. Our results is consistent with the value of this coupling constant obtained using vector meson dominance of the electromagnetic current and the experimental ρ-photoproduction data.

متن کاملUnitary Structure of the QCD Sum Rules and KYN and KYΞ Couplings
New relations between QCD Borel sum rules for strong coupling constants of K-mesons to baryons are derived. It is shown that starting from the sum rule for the coupling constants gπΣΣ and gπΣΛ it is straightforward to obtain corresponding sum rules for the gKY N , gKY Ξ couplings, Y = Σ,Λ.
متن کاملCoupling constants ga0ωγ and ga0ργ as derived from QCD sum rules
We consider the two point correlation function of scalar current in QCD sum rules approach to estimate the overlap amplitude of a0 meson. We then employ QCD sum rules to calculate the coupling constants gωa0γ and gρa0γ by studying the three point a0ωγand a0ργ-correlation functions.

متن کاملThe effect of Bπ continuum in the QCD sum rules for the (0, 1) heavy meson doublet in HQET
We study the effect of Bπ continuum in the QCD sum rule analysis of the heavy meson doublet (0+, 1+) in the leading order of heavy quark effective theory. New sum rules are derived for the leading order binding energy Λ̄+, 1 2 and pionic coupling constant g′. PACS number: 12.39.Hg, 11.30.Rd, 13.20.He, 12.38.Lg
متن کاملNew QCD Sum Rules for Nucleon Axial Vector Coupling Constants
Two new sets of QCD sum rules for the nucleon axial coupling constants are derived using the external-field technique and generalized interpolating fields. An in-depth study of the predicative ability of these sum rules is carried out using a Monte-Carlo based uncertainty analysis. The results show that the standard implementation of the QCD sum rule method has only marginal predicative power f...
