A theory of lepton decay constants based on the path-integral formalism is given for chiral and vector mesons. Decay constants of the pseudoscalar and vector mesons are calculated and compared to other existing results.

Scalar mesons in a chiral theory with quark degrees of freedom
The chiral confining Lagrangian, based on chiral theory with quark degrees of freedom, is used to study the spectroscopy of scalar mesons. The formalism does not contain arbitrary fitting parameters,
Chiral Lagrangian and chiral quark model from confinement in QCD
The effective chiral Lagrangian in both nonlocal form LECCL and standard local form LECL, derived in the vacuum correlator formalism in QCD, is studied in the chiral perturbation theory. It is shown,

TLDR
The three quark system is studied in a relativized version of the quark potential model with chromodynamics and the spectrum of baryons is described with parameters consistent with those of an analogous study of meson spectroscopy.

Spectroscopy of Bc mesons in the relativized quark model
We calculate the spectrum of the charm-beauty mesons using the relativized quark model. Using the wave functions from this model we compute the radiative widths of excited cb states. The hadronic

We discuss the spectrum of hadrons with a heavy colour-adjoint particle - motivated by the gluino of supersymmetry. Using the lattice approach, we explore in detail the gluonic bound states - the
