Hamilton-Jacobi Quantization of Landau-Ginzburg Theory

We discuss the Hamilton-Jacobi approach for a constrained system. We obtain the equation of motion for a singular system as total differential equations in many variables. We investigate the integrability conditions without using any gauge fixing condition. The path integral quantization for systems with finite degrees of freedom is applied to the field theories with constraints. So, we apply the Hamilton-Jacobi quantization to obtain the path integral of the Landau-Ginzburg theory.

Interaction of the pseudoscalar glueball with (pseudo)scalar mesons and nucleons

We study the interactions of the pseudoscalar glueball with scalar and pseudoscalar quark-antiquark meson fields and with the nucleon and its chiral partner. In both cases we introduce the corresponding chiral Lagrangian and discuss its properties. We calculate the mesonic and baryonic decays of a pseudoscalar glueball with mass of about 2.6 GeV as predicted by Lattice simulations.
