Kaluza-Klein Spectroscopy from Neutron Oscillations into Hidden Dimensions
Gia Dvali, Manuel Ettengruber, Anja Stuhlfauth
Neutrons and neutrinos are natural probes for new physics. Since they carry no conserved gauge quantum numbers, both can easily mix with the fermions from hidden sectors. A particu…
How Many Dark Neutrino Sectors Does Cosmology Allow?
Alan Zander, Manuel Ettengruber, Philipp Eller
We present the very first constraints on the number of Standard Model (SM) copies with an additional Dirac right-handed neutrino. From cosmology, we are able to pose strong limits…
Consequences of Multiple Axions in Theories with Dark Yang-Mills Groups
Manuel Ettengruber, Emmanouil Koutsangelas
General consistency requirements of Quantum Gravity demand the existence of one axion per Yang-Mills group. In this work, we consider theories with dark Yang-Mills sectors and inve…
