Constant matter neutrino oscillations in a parametrization-free formulation.
Description
Neutrino oscillations are now a well-stablished and deeply studied
phenomena. Their mixing parameters, except for the CP phase, are
measured with good accuracy. The three-neutrino oscillation picture in
matter is currently of great interest due to the different
long-baseline neutrino experiments that are already running or under
construction. In this work, we reanalyze the exact expression for the
neutrino probabilities (in a constant density medium) and introduce an
approximate formula. Our results are shown in a formulation that is
independent of the parametrization and could be useful for unitary
tests of the leptonic mixing matrix. We illustrate how the
approximation, besides being simple, can reproduce the neutrino
probabilities with good accuracy.
