TITLE:

 HADONIC SPECTROSCOPY VIA AN EFFECTIVE APPROACH TO QUANTUM CHROMODYNAMICS


KEY WORDS:

Effective hamiltonian, QCD in Coulomb gauge, Meson spectrum, Many-body techniques.


PAGES: 103
BIG AREA: Ciências Exatas e da Terra
AREA: Física
SUMMARY:
We seek in this work to discuss and characterize the spectrum of tensor mesons 2−(−)
and mesons Bc with different quantum numbers (JP = 0−,0+,1−,1+,2+,2−), making use of the Hamiltonian approach of
QCD in the Coulomb Gauge with the aid of a so-called Tamm-Dancoff approximation, having the interac-
tions given by an improved confinement potential and a transverse hyperfine interaction, whose kernel is
a Yukawa-like potential. Through this model we have a unified treatment of the different types of quarks
using a minimum number of free parameters to have a basic profile of the mesonic spectra. Regge tra-
jectories relating the fundamental and radially excited states are constructed and the hyperfine separations
analyzed. Finally, we make comparisons of the numerical results obtained with experimental data and
theoretical predictions from other models.
