Decays of tensor mesons and the tensor glueball in an effective field approach
F. Giacosa, Th. Gutsche, V. E. Lyubovitskij +1
The strong and electromagnetic decays of the ground-state tensor mesons are studied in an effective field approach. A fit to the well-known experimental data is performed. The deca…
Chiral Dynamics of Baryons in a Lorentz Covariant Quark Model
Amand Faessler, Th. Gutsche, V. E. Lyubovitskij +1
We develop a manifestly Lorentz covariant chiral quark model for the study of baryons as bound states of constituent quarks dressed by a cloud of pseudoscalar mesons. The approach…
Strong CP violation and the neutron electric dipole form factor
J. Kuckei, Claudio Dib, Amand Faessler +4
We calculate the neutron electric dipole form factor induced by the CP violating theta-term of QCD, within a perturbative chiral quark model which includes pion and kaon clouds. On…

Scalar nonet quarkonia and the scalar glueball: mixing and decays in an effective chiral approach
F. Giacosa, Th. Gutsche, V. E. Lyubovitskij +1
We study the strong and electromagnetic decay properties of scalar mesons above 1 GeV within a chiral approach. The scalar-isoscalar states are treated as mixed states of quarkonia…
Nucleon polarizabilities in the perturbative chiral quark model
Y. Dong, Amand Faessler, Th. Gutsche +4
The nucleon polarizabilities alpha(E) and beta(M) are studied in the context of the perturbative chiral quark model. We demonstrate that meson cloud effects are sufficient to expla…
Scalar meson mediated nuclear mu-e conversion
Amand Faessler, Th. Gutsche, Sergey Kovalenko +2
We study the nuclear mu-e conversion in the general framework of the effective Lagrangian approach without referring to any specific realization of the physics beyond the standard…
Quark model description of quasi-elastic pion knockout from the proton at JLAB
I. T. Obukhovsky, D. Fedorov, Amand Faessler +2
The interference term between s- and t-pole contributions to the p(e,e' pi+)n cross section is evaluated on the basis of the constituent quark model. It is shown that the contribut…
Scalar meson and glueball decays within a effective chiral approach
F. Giacosa, Th. Gutsche, V. E. Lyubovitskij +1
We study the strong and electromagnetic decay properties of scalar mesons above 1 GeV within a chiral approach. The scalar-isoscalar states are treated as mixed states of quarkonia…
