Ultra-cold neutrons in qBounce experiments as laboratory for test of chameleon field theories and cosmic acceleration
Derar Altarawneh, Roman Höllwieser
The accelerating expansion of the Universe, attributed to dark energy, has spurred interest in theories involving scalar fields such as chameleon field theories. These fields, whic…
Theoretical description of the neutron beta decay in the standard model at the level of 10^{-5}
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
In the framework of the Standard Model (SM) a theoretical description of the neutron beta decay is given at the level of 10^{-5}. The neutron lifetime and correlation coefficients…
On the structure of the correlation coefficients S(E_e) and U(E_e) of the neutron beta decay
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
In the standard effective V - A theory of low-energy weak interactions (i.e. in the Standard Model (SM)) we analyze the structure of the correlation coefficients S(E_e) and U(E_e),…
Influence of Fermions on Vortices in SU(2)-QCD
Sedigheh Deldar, Zeinab Dehghan, Manfried Faber +2
Gauge fields control the dynamics of fermions, also a back reaction of fermions on the gauge field is expected. This back reaction is investigated within the vortex picture of the…
Test of the Standard Model in Neutron Beta Decay with Polarized Electron and Unpolarized Neutron and Proton
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
We calculate the correlation coefficients of the electron-energy and electron-antineutrino angular distribution of the neutron beta decay with polarized electron and unpolarised ne…
Neutron Dark Matter Decays
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
We analyse the discrepancy between the neutron lifetimes measured in the bottle and beam experiments. Following Fornal and Grinstein (Phys. Rev. Lett. 120, 191801 (2018)) we propos…
