Rare semileptonic decay of $χ_{c 1} (1 p)$ meson In QCD

N. Ghahramany, A. R. Houshyar

The rare semileptonic $χ_{c 1} (1 p) \to D_{s}^{+} e ν ˉ$ decay is analyzed, by using the three-point QCD sum rules. Taking into account the two-gluon condensate contribution…

Coupling constants of bottom (charmed) mesons with pion from three point QCD sum rules

M. Janbazi, N. Ghahramany, E. Pourjafarabadi

In this article, the three point QCD sum rules is used to compute the strong coupling constants of vertices containing the strange bottomed ( charmed ) mesons with pion. The coupli…

Semileptonic $B_{c}^{-} \to D^{* 0} ℓ ν$ transition in three--point QCD sum rules and HQET with gluon condensate corrections

N. Ghahramany, R. Khosravi, K. Azizi

Taking into account the gluon condensate contributions, the form factors of the semileptonic $B_{c}^{-} \to D^{* 0} ℓ ν$ transition with $l = τ, e$ are calculated in the framework of the…

Semileptonic $D_{q} \to K_{1} ℓ ν$ and nonleptonic $D \to K_{1} π$ decays in three--point QCD sum rules and factorization approach

R. Khosravi, K. Azizi, N. Ghahramany

We analyze the semileptonic $D_{q} \to K_{1} ℓ ν$ transition with $q = u, d, s$ , in the framework of the three--point QCD sum rules and the nonleptonic $D \to K_{1} π$ decay within the Q…

Kaon Electroproduction off Proton

N. Ghahramany, M. Ghanaatian

The elementary reaction of kaon exclusive electroproduction on protons has been studied in a broad kinematical range. Data for the calculation of the form factor of the kaon have b…
