Abstract
|
A nonperturbative Hamiltonian of bound state refers to a Hamiltonian operator that cannot be treated using perturbation theory. Perturbation theory is a mathematical approach used to solve problems when the Hamiltonian can be separated into a solvable unperturbed part and a perturbation that is small compared to the unperturbed part. Solving nonperturbative Hamiltonians typically requires the use of more advanced techniques, such as numerical methods or approximation schemes specifically designed for nonperturbative systems, which is a great deal of interest in nuclear and particle physics. We calculate the mass spectrum and constituent mass of particles in a bound state using the Bethe–Salpeter equation with 𝑈(𝑟) = 𝑈𝑣(𝑟) + 𝑈𝑠(𝑟) potential of interaction at high energy and relativistic limits. Therefore, the most essential issue in theoretical particle research is to explain the Einsteinian adjustment of higher bound states, in order to determine the characteristics of relativistic effects within the potential interaction and kinetic energy. We present the method based on quantum field theory and Feynman path integral to calculate the mass spectra of hadrons.
