چکیده
The integration is carried out in the reference frame in which the spatial components of P, are zero and the dimensionless quantities cr = l4/222 and c=Fp/m are introduced. The real part of 8M is obtained by straightforward integration with absolute value signs placed on the argument of the logarithm: Re 5M = (3g2/162r2) m( —1+2n2+ (1+3422 2c24+ (422—1)/e') in~+ ccp (2422—7) (4—c22)—*' Xtan-'a(4 —~2)&——;B(e)InF(e) + ,ape-'r 2 3c— 42+ (1 n')/—e' (1+—442' 3424+2422/e2 (1 422)2/e4) in~ —np (3422—10)(4—c22) l tan-'cr (4—422)—& +(1-(--1)/")-:B()1~()».

Covariant meson - baryon scattering with chiral and large N c constraints 1
We give a review of recent progress on the application of the relativistic chiral SU (3) Lagrangian to meson-baryon scattering. It is shown that a combined chi-ral and 1/N c expansion of the Bethe-Salpeter interaction kernel leads to a good description of the kaon-nucleon, antikaon-nucleon and pion-nucleon scattering data typically up to laboratory momenta of p lab ≃ 500 MeV. We solve the covar...
متن کاملNucleon mass from a covariant three-quark Faddeev equation.
We report the first study of the nucleon where the full Poincaré-covariant structure of the three-quark amplitude is implemented in the Faddeev equation. We employ an interaction kernel which is consistent with contemporary studies of meson properties and aspects of chiral symmetry and its dynamical breaking, thus yielding a comprehensive approach to hadron physics. The resulting current-mass e...
متن کامل71 v 1 2 7 O ct 1 99 8 Covariant representations of the relativistic Brueckner T - matrix and the nuclear matter problem
We investigate nuclear matter properties in the relativistic Brueckner approach. The in-medium on-shell T-matrix is represented covariantly by five Lorentz invariant amplitudes from which we deduce directly the nucleon self-energy. We discuss the ambiguities of this approach and the failure of previously used covariant representations in reproducing the nucleon self-energies on the Hartree-Fock...
متن کاملPion - nucleon interaction in a covariant hadron - exchange model
We develop a relativistic covariant and unitary description of the pion-nucleon interaction in a hadron-exchange model. The model is based on the solution of a dimensionally reduced (quasipotential) Bethe-Salpeter equation for the partial-wave off-shell πN scattering amplitudes with the potential consisting of the field-theoretical sand u-channel nucleon, Roper, Delta, D13, S11 exchanges, and t...
متن کاملRelativistic chiral SU ( 3 ) symmetry , large N c sum rules and meson - baryon scattering
The relativistic chiral SU (3) Lagrangian is used to describe kaon-nucleon scattering imposing constraints from the pion-nucleon sector and the axial-vector coupling constants of the baryon octet states. We solve the covariant coupled-channel Bethe-Salpeter equation with the interaction kernel truncated at chiral order Q 3 where we include only those terms which are leading in the large N c lim...
متن کاملCovariant L - S Scheme for the effective N ∗ NM couplings
For excited nucleon states N of arbitrary spin coupling to nucleon (N) and meson (M), we propose a Lorentz covariant orbital-spin (L-S) scheme for the effective NNM couplings. To be used for the partial wave analysis of various N production and decay processes, it combines merits of two conventional schemes, i.e., covariant effective Lagrangian approach and multipole analysis with amplitudes ex...
