Quantum gravitational states of ultracold neutrons as a tool for probing of beyond-Riemann gravity
A. N. Ivanov, M. Wellenzohn, H. Abele
We analyze a possibility to probe beyond-Riemann gravity (BRG) contributions, introduced by Kostelecky and Li (see Phys. Rev. D 103, 024059 (2021) and Phys. Rev. D 104, 044054 (202…
Corrections of order O(E^2_e/m^2_N), caused by weak magnetism and proton recoil, to the neutron lifetime and correlation coefficients of the neutron beta decay
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
We calculate the contributions of weak magnetism and proton recoil of order O(E^2_e/m^2_N)~10^{-5}, i.e. to next-to-next-to-leading order in the large nucleon mass expansion, to th…
Proof of Principle for Ramsey-type Gravity Resonance Spectroscopy with qBounce
René I. P. Sedmik, Joachim Bosina, Lukas Achatz +10
Ultracold neutrons (UCNs) are formidable probes in precision tests of gravity. With their negligible electric charge, dielectric moment, and polarizability they naturally evade som…
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…
Electrodisintegration of Deuteron into Dark Matter and Proton Close to Threshold
A. N. Ivanov, R. Höllwieser, N. I. Troitskaya +2
We discuss an investigation of the dark matter decay modes of the neutron, proposed by Fornal and Grinstein (Phys. Rev. Lett. 120 191801 (2018)) and Ivanov et al. ( arXiv:1806.1010…
Gravity Resonance Spectroscopy Constrains Dark Energy and Dark Matter Scenarios
T. Jenke, G. Cronenberg, J. Burgdörfer +9
We report on precision resonance spectroscopy measurements of quantum states of ultracold neutrons confined above the surface of a horizontal mirror by the gravity potential of the…
