Spin precession and neutrino helicity flip in various spacetimes
Reza Saadati, Fayçal Hammad, Santiago Novoa-Cattivelli +2
We systematically study spin precession of neutral particles freely moving in spacetime. We first derive the formula describing spin precession within a general stationary and axis…

Neutrino spin oscillation in screening models revisited
Fayçal Hammad, Nicolas Fleury, Parvaneh Sadeghi
We study, using the Mathisson-Papapetrou-Dixon equations, the spin oscillation of neutrinos when the latter are coupled to the scalar field of screening models of dark energy. Firs…
