We identify the recently observed charmoniumlike structure Z c±(3900) as the charged
partner of the X (3872) state. Using standard techniques of QCD sum rules, we evaluate the …

The H∗ Hπ form factor for H= B and D mesons is evaluated in a QCD sum rule calculation.
We study the Borel sum rule for the three point function of two pseudoscalar and one vector …

We study the two point-function for the scalar mesons σ, κ, f0 (980) and a0 (980) as diquak–
antidiquark states. We also study the decays of these mesons into ππ, Kπ and KK¯. We find …

Coupling constants of the pseudoscalar mesons to the octet baryons are calculated in the
QCD sum rule approach. Two-point correlation function of the baryons are evaluated in a …

A phenomenological model for the KN → K Ξ reaction is suggested. The model includes s
and u channel exchanges by Λ, Σ, Σ (1385), and Λ (1520) and s channel exchanges by …

The NKY coupling constant for Y= Λ and Σ is evaluated in a QCD sum rule calculation. We
study the Borel sum rule for the three point function of one pseudoscalar one nucleon and …

For the study of the structure of baryons it is necessary to investigate the production of a
baryon pair in e+ e-annihilation. The baryon-antibaryon pair production at the electron …

The strong coupling constants g Σ Q Λ Q π (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 …

The coupling constants of K and π mesons with the octet baryons are studied in light cone
QCD sum rules taking into account SU (3) f flavor symmetry breaking effects, but keeping the …

In the present paper, we investigate the production of a baryon pair in $ e^+ e^-$
annihilation to study the structure of baryons. To study the basic structure of the Standard …
