CP-violating decays of the pseudoscalars eta and eta' and their connection to the electric dipole moment of the neutron
Thomas Gutsche, Astrid N. Hiller Blin, Sergey Kovalenko +4
Using the present upper bound on the neutron electric dipole moment, we give an estimate for the upper limit of the CP-violating couplings of the eta(eta') to the nucleon. Using th…
Effect of the channel and interference phenomena in the two-pion transitions of charmonia and bottomonia
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by an unified mechanism based on contributions of the ,…
The interference effects of multi-channel pion-pion scattering contributions to the final states of - and -meson family decays
Yu. S. Surovtsev, P. Bydžovský, T. Gutsche +3
It is shown that the basic shape of dipion mass distributions in the two-pion transitions of both charmonia and bottomonia states are explained by an unified mechanism based on the…
Nucleon parton distributions in a light-front quark model
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt
Continuing with our analysis of parton distributions in the nucleon, we extend our light-front quark model in order to obtain both the helicity independent and helicity dependent p…
Four-quark structure of Zc(3900), Z(4430) and Xb(5568) states
Fabian Goerke, Thomas Gutsche, Mikhail A. Ivanov +3
We examine the four-quark structure of the recently discovered charged , , and states. We calculate the widths of the strong decays $Z_c^+ \to J/ψπ^…
Nucleon tensor form factors in a relativistic confined quark model
Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2
We present results for the isotriplet and isosinglet tensor form factors of the nucleon in the relativistic confined quark model. The model allows us to calculate not only their no…
