Effects of a torsion field on Big Bang nucleosynthesis
M. Brüggen
In this paper it is investigated whether torsion, which arises naturally in most theories of quantum gravity, has observable implications for the Big Bang nucleosynthesis. Torsion…

Neutrino spin-flips in curved space-time
M. Bruggen
The general relativistic effects on spin-flavor oscillations above the core of type II supernovae are investigated. The evolution equation is derived and the relative magnitudes of…

Spin-Flavour Oscillations and Neutrinos from SN1987A
M. Brüggen
The neutrino signal from SN1987A is analysed with respect to spin-flavour oscillations between electron antineutrinos, , and muon neutrinos, , by means of a maximum…
