A solution of the Schrödinger equation written in terms of hyperspherical Jacobi coordinates is presented. The wave function and the potential are projected onto the space of a single reference pair Jacobi coordinate. The ground state binding energi

A method is proposed to obtain a translationnaly invariant solution to the Schrodinger equation including two-body correlation. The conditions to obtain translationnaly invariant excited state are discussed. It is explained why ground states are surr

Starting from the Schr6dinger equation, a new Variational Integro-Differential Equation (VIDE) for three bosons in S-state is derived. The wave function has the simple structure of a sum of two-body amplitudes. It is shown that the new equation gives

Integro-differential equations avoiding the ghost contributions occuring in the Faddeev amplitudes are derived for a system of three identical particles in S-states. The equation for the mixed-symmetry state is given for the case of nucleons. Equatio

In the integro-differential-equation approach (IDEA) and its associated hyperspherical-harmonic expansion method (HHEM) terms appear involving the potential for a single pair of particles. This introduces a spurious component in the potential that is

One way to reduce the large degeneracy of the hyperspherical-harmonic basis for solving few- and many-body bound-state problems is to introduce an optimal basis truncation called the potential-harmonic (PH) basis. In this paper we introduce various p

Baryon structure and baryon Regge trajectories are studied in a relativistic approach based on the method of vacuum correlators. Generation of constituent mass for quarks and diquarks is studied quantitatively for baryons with angular momenta up to L

The authors show that for the 4He ground state and effective potentials the integrodifferential equation approach (IDEA) produces binding energies which are more accurate than those calculated using a harmonic oscillator shell model basis and require
