Analysis of the strong coupling form factors of bNB andcND in QCD sum rules

  • In this article, we study the strong interaction of the vertices bNB and cND using the three-point QCD sum rules under two different Dirac structures. Considering the contributions of the vacuum condensates up to dimension 5 in the operation product expansion, the form factors of these vertices are calculated. Then, we fit the form factors into analytical functions and extrapolate them into time-like regions, which gives the coupling constants. Our analysis indicates that the coupling constants for these two vertices are GbNB=0.43±0.01 GeV-1 and GcND=3.76±0.05 GeV-1.

Abstract: In this article, we study the strong interaction of the vertices bNB and cND using the three-point QCD sum rules under two different Dirac structures. Considering the contributions of the vacuum condensates up to dimension 5 in the operation product expansion, the form factors of these vertices are calculated. Then, we fit the form factors into analytical functions and extrapolate them into time-like regions, which gives the coupling constants. Our analysis indicates that the coupling constants for these two vertices are GbNB=0.43±0.01 GeV-1 and GcND=3.76±0.05 GeV-1.
