The linear radial spectrum of scalar mesons within the QCD sum rules in the planar limit
S. S. Afonin, T. D. Solomko
We discuss the radial spectrum of light scalar mesons in the framework of spectral sum rules in the large-Nc (planar) limit of QCD. Two methods based on the use of linear radial Re…
Large- masses of light mesons from QCD sum rules for non-linear radial Regge trajectories
S. S. Afonin, T. D. Solomko
The large- masses of light vector, axial, scalar and pseudoscalar mesons are calculated from QCD spectral sum rules for a particular ansatz interpolating the radial Regge traj…
Electromagnetic couplings of radially excited light vector mesons from QCD sum rules
S. S. Afonin, T. D. Solomko
The couplings of unflavored vector mesons to the annihilation are an important source of information on the nature and structure of these resonances which play a prominent…
The large-Nc limit of borelized spectral sum rules and the slope of radial Regge trajectories
S. S. Afonin, T. D. Solomko
We put forward a new phenomenological method for calculating the slope of radial trajectories from values of ground states and vacuum condensates. The method is based on a large-$N…
