Neutrino Oscillation Caused by Spacetime Geometry
The effects of gravitational interaction are generally neglected in particle physics. A first-order formulation
of gravity is presented to include gravity in the Quantum Mechanical Lagrangian of fermions. It is seen that
fermions minimally coupled to gravity give rise to a torsionless effective theory with a quartic interaction.
After passing through a thermal background, the most generic form of contortion contributes to neutrino
effective mass. This effective mass can change the current oscillation parameters.
