ΣQΛQπ Coupling Constant in Light Cone QCD Sum Rules
The strong coupling constants gΣQΛQπ (Q = b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the ΣQ −→ ΛQπ decays which are compared with the predictions of the other approaches and existing experimental data.

متن کامل∆πN coupling constant in light cone QCD sum rules
We employ the light cone QCD sum rules to calculate ∆πN coupling constant by studying the two point correlation function between the vacuum and the pion state. Our result is consistent with the traditional QCD sum rules calculations and it is in agreement with the experimental value. ∗[email protected] †[email protected]

In this article, we take the point of view that the light scalar meson a0(980) is a conventional qq̄ state, and calculate the coupling constants ga0ηπ0 and ga0η′π0 with the light-cone QCD sum rules. The central value of the coupling constant ga0ηπ0 is consistent with the one extracted from the radiative decay φ(1020) → a0(980)γ → ηπ0γ. The central value and lower bound of the decay width Γa0→ηπ0...

متن کاملpπ with light - cone QCD sum rules
In this article, we calculate the strong coupling constant g∆Nπ and study the strong decay ∆++ → pπ with the light-cone QCD sum rules. The numerical value of the strong coupling constant g∆Nπ is consistent with the experimental data. The small discrepancy maybe due to failure to take into account the perturbative O(αs) corrections.
