Chiral symmetry restoration in strange hadronic matter
P. Wang, V. E. Lyubovitskij, Th. Gutsche +1
The phase transition of chiral symmetry restoration in strange hadronic matter is studied in the chiral SU(3) quark mean field model. When the baryon density is larger than a criti…
Updated analysis of meson-nucleon sigma terms in the perturbative chiral quark model
T. Inoue, V. E. Lyubovitskij, Th. Gutsche +1
We present an updated analysis of meson-baryon sigma terms in the perturbative chiral quark model, which is based on effective chiral Lagrangian. The new feature concerns the inclu…
Expectation values of four-quark operators in the nucleon
E. G. Drukarev, M. G. Ryskin, V. A. Sadovnikova +3
We calculate expectation values of QCD operators consisting of the products of the four operators of the light quarks corresponding to the scalar, pseudoscalar, vector, pseudovecto…
Electromagnetic nucleon-delta transition in the perturbative chiral quark model
K. Pumsa-ard, V. E. Lyubovitskij, Th. Gutsche +2
We apply the perturbative chiral quark model to the gamma N -> Delta transition. The four momentum dependence of the respective transverse helicity amplitudes A(1/2) and A(3/2) is…
Pion and sigma meson properties in a relativistic quark model
Amand Faessler, Th. Gutsche, M. A. Ivanov +2
A variety of strong and electroweak interaction properties of the pion and the light scalar sigma meson are computed in a relativistic quark model. Under the assumption that the re…
