The $ρ (1 S, 2 S)$ , $ψ (1 S, 2 S)$ , $Υ (1 S, 2 S)$ and $ψ_{t} (1 S, 2 S)$ mesons in a double pole QCD Sum Rule

M. S. Maior de Sousa, R. Rodrigues da Silva

We use the method of double pole QCD sum rule which is basically a fit with two exponentials of the correlation function, where we can extract the masses and decay constants of mes…

Are $Θ^{+}$ and the Roper resonance diquark-diquark-antiquark states?

R. D. Matheus, F. S. Navarra, M. Nielsen +2

We consider a $[u d]^{2} s ˉ$ current in the QCD sum rule framework to study the mass of the recently observed pentaquark state $Θ^{+} (1540)$ , obtaining good agreement with the exper…

The $J / ψ D D^{*}$ vertex

R. Rodrigues da Silva, R. D. Matheus, F. S. Navarra +1

We employ QCD sum rules to calculate the $J / ψ D D^{*}$ form factors and coupling constant by studying the three-point $J / ψ D^{*} D$ correlation function. We find that the momentum dependen…

The $J / ψ D D$ Vertex in QCD Sum Rules

R. D. Matheus, F. S. Navarra, M. Nielsen +1

The $J / ψ D D$ form factor is evaluated in a QCD sum rule calculation for both $D$ and $J / ψ$ off-shell mesons. We study the double Borel sum rule for the three point function of two…
