Comment on "Relativistic cluster dynamics of nucleons and mesons. II. Formalism and examples"

چکیده
In a recent paper [Phys. Rev. C49, 2142 (1994)], Haberzettl presented cluster N-body equations for arbitrarily large systems of nucleons and mesons. Application to the three-nucleon system is claimed to yield a new kind of three-nucleon force. We demonstrate that these three-nucleon equations contain double counting. 21.30.+y, 21.45+v, 21.60.-n, 21.60.Gx Typeset using REVTEX

Relativistic Hamiltonians in many-body theories.
We discuss the description of a many-body nuclear system using Hamilto-nians that contain the nucleon relativistic kinetic energy and potentials with relativistic corrections. Through the Foldy-Wouthuysen transformation, the field theoretical problem of interacting nucleons and mesons is mapped to an equivalent one in terms of relativistic potentials, which are then expanded at some order in 1/...
متن کاملVariational Calculations for the Relativistic Interacting Fermion System at Finite Temperature: Application to Liquid 3He
In this paper, at first we have formulated the lowest order constrained variational method for the relativistic case of an interacting fermion system at finite temperature. Then we have used this formalism to calculate some thermodynamic properties of liquid in the relativistic regime. The results show that the difference between total energies of relativistic and non-relativistic cases of liqu...
متن کاملA relativistic model for neutrino pion production from nuclei in the resonance region
We present a relativistic model for electroweak pion production from nuclei, focusing on the ∆ and the second resonance region. Bound states are derived in the Hartree approximation to the σ − ω Walecka model. Final-state interactions of the outgoing pion and nucleon are described in a factorized way by means of a relativistic extension of the Glauber model. Our formalism allows a detailed stud...
متن کاملElectromagnetic scattering from relativistic bound states.
The quasipotential formalism for elastic scattering from relativistic bound states is formulated based on the instant constraint in the Breit frame. The quasipotential electromagnetic current is derived from Mandelstam's vepoint kernel and obeys a two-body Ward identity. Breit-frame wave functions are obtained directly by solving integral equations with nonzero total threemomentum, thus accompl...
متن کاملTime Dependent Relativistic Mean-field Theory
The relativistic mean-field theory provides a framework in which the nuclear manybody problem is described as a self-consistent system of nucleons and mesons. In the mean-field approximation, the self-consistent time evolution of the nuclear system describes the dynamics of collective motion: double giant resonances, nuclear compressibility from monopole resonances, regular and chaotic dynamics...
