Hadronic spectroscopy via QCD no gauge of
Coulomb
Espectroscopia hadrônica, QCD ,gauge de Coulomb
The objective of this work is the analysis of axial resonances and exotic states in
sectors of the foreigner, botomônio and charmônio. We use a method that
the exact QCD Hamiltonian in the Coulomb gauge by an effective Hamiltonian with
a confining potential and a transverse hyperfine interaction. A transformation
of similarity (BCS) is applied, diagonalizing the Hamiltonian in a new base of
quasiparticles. We apply, then, variational calculations to obtain the equation of
the quasiparticle mass gap, and we used the RPA and the TDA to represent the
excited.
