Hadronic matrix elements of gluon operators in the instanton vacuum
D. I. Diakonov, M. V. Polyakov, C. Weiss
We propose a method to evaluate hadronic matrix elements of QCD gluon operators in the instanton vacuum. We construct the ground state of the interacting instanton ensemble for non…
Analytic structure of meson propagators in the proper-time regularized Nambu--Jona-Lasinio model
W. Broniowski, G. Ripka, E. Nikolov +1
We analyze the analytic structure of meson propagators in the Nambu--Jona-Lasinio model with a proper-time regulator. We show that the regulator produces unphysical complex singula…
Strangeness in the Scalar Form Factor of the Nucleon
Hyun-Chul Kim, Andree Blotz, Carsten Schneider +1
The scalar form factor of the nucleon and related physical quantities are investigated in the framework of the semibosonized SU(3) Nambu-Jona-Lasinio soliton model. We take into ac…
Electromagnetic form factors of the nucleon in the chiral quark soliton model
Chr. V. Christov, A. Z. Górski, K. Goeke +1
In this paper we present the derivation as well as the numerical results for the electromagnetic form factors of the nucleon within the chiral quark soliton model in the semiclassi…
Magnetic Moments of the SU(3) Octet Baryons in the semibosonized SU(3) Nambu-Jona-Lasinio Model
H. -C. Kim, M. V. Polyakov, A. Blotz +1
We investigate the magnetic moments of the SU(3) octet baryons in the framework of the semibosonized Nambu--Jona--Lasinio model. The rotational corrections and stra…
Elusive exotic states
Hyun-Chul Kim, Mikhail Shmatikov
The existence of flavor exotic molecular-type states is investigated. An attractive force between two {\it pseudoscalar} heavy meson is generate…
The Constituent Quark Limit and the Skyrmion Limit of the Chiral Quark Soliton Model
M. Praszalowicz, A. Blotz, K. Goeke
We calculate and in the Chiral Quark-Soliton Model (or equivalently in semibosonized Nambu--Jona-Lasinio model) in the limit of small and large soliton size. In sma…
Curvature Radiation by Ultrarelativistic Protons
V. Berezinsky, A. Dolgov, M. Kachelriess
We study pion curvature radiation by a proton, i.e. pion emission by a proton moving along a curved trajectory. We suggest an approximate semiclassical solution and the exact solut…
Electromagnetic Form Factors of the SU(3) Octet Baryons in the semibosonized SU(3) Nambu-Jona-Lasinio Model
Hyun-Chul Kim, Andree Blotz, Maxim V. Polyakov +1
The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu--Jona-Lasinio model (chiral quark-soliton model). The rotational $1/N_…
Ratio for the Transition in the Chiral Quark Soliton Model
T. Watabe, Chr. V. Christov, K. Goeke
We calculate the electric quadrupole to magnetic dipole transition ratio for the reaction $γN \ra Δ(1232)$ in the chiral quark soliton model. The calculated ratio i…
Baryon form factors in a diquark-quark bound state description
G. Hellstern, C. Weiss
Nucleon form factors are calculated in a relativistic diquark--quark picture based on the Nambu--Jona-Lasinio model. The nucleon wave function is obtained in a static approximation…
Hadronic molecules: meson-baryon hybrids
M. Shmatikov
The existence of hadronic molecular-type hybrids consisting of a baryon and a meson is argued. Long-range interactions due to one-pion exchange is shown to be strong enough to prod…
