Abstract

A relativistic generalization of three-quark Faddeev equations for the particles of the (70, 1{sup -}) multiplet is constructed within the dispersion-relation approach. An approximate solution to the relativistic three-quark equations is obtained on the basis of the method of isolating leading singularities of scattering amplitudes. The mass spectrum of the (70, 1{sup -}) multiplet is calculated, and the result is in rather good agreement with corresponding experimental data.

Excited (70,L{sup +}) baryons in a relativistic quark model

Journal Article Gerasyuta, S M ; Matskevich, E E - Physical Review. D, Particles Fields

The masses of positive parity (70,0{sup +}) and (70,2{sup +}) nonstrange and strange baryons are calculated in the relativistic quark model. The relativistic three-quark equations of the (70,L{sup +}) multiplets are found in the framework of the dispersion relation technique. The approximate solutions of these equations using the method based on the extraction of leading singularities of the amplitude are obtained. The calculated mass values of the (70,L{sup +}) multiplets are in good agreement with the experimental ones.

Electroexcitation of nucleon resonances of the $[70, 1^{-}]$ multiplet in a light-front relativistic quark model

Journal Article Aznauryan, I. G. ; Burkert, V. D. - Physical Review C

We utilize the light-front relativistic quark model to predict the 3q core contribution to the electroexcitation of nucleon resonances of the [70,1 ^–] multiplet on the proton and neutron at Q ² < 5 GeV ². The investigation is motivated by new experimental data from continuous electron beam accelerator facility large acceptance spectrometer on meson electroproduction for a wide range of the hadronic invariant mass including the full third nucleon resonance region up to √s = 1.8 GeV. For the states N(1520)3/2 ^–, N(1535)1/2 ^–, and N(1675)5/2 ^–, experimental results on the electroexcitation amplitudes on the proton are available formore »« less

Relativistic five-quark equations and exotic baryons with isospin I=5/2

Journal Article Gerasyuta, S M ; Department of Physics, LTA, 194021 St. Petersburg ; Kochkin, V I - Physical Review. D, Particles Fields

The relativistic five-quark equations are found in the framework of the dispersion relation technique. The five-quark amplitudes for the low-lying exotic baryons including the u, d quarks are calculated. The poles of the five-quark amplitudes determine the masses and the widths of uuuud and ddddu states (isospin I=5/2). The mass spectrum of the E{sup +++} exotic baryons with J{sup P}=(1{sup +}/2), (3{sup +}/2), (5{sup +}/2) is calculated.

Relativistic five-quark equations and negative parity pentaquarks

Journal Article Gerasyuta, S M ; Department of Physics, LTA, 194021, St. Petersburg ; Kochkin, V I - Physical Review. D, Particles Fields

The relativistic five-quark equations are found in the framework of the dispersion relation technique. The solutions of these equations using the method based on the extraction of the leading singularities of the amplitudes are obtained. The five-quark amplitudes for the low-lying pentaquarks including the u, d, s quarks are calculated. The poles of these amplitudes determine the masses of the negative parity pentaquarks with I=0,1 and J{sup P}=(3/2){sup -},(5/2){sup -}. The mass of the lowest pentaquark with I=0 and J{sup P}=(3/2){sup -} is equal to 1514 MeV.
