An accurate analytic description of neutrino oscillations in matter — •Viviana Niro — Max-Planck-Institut fuer Kernphysik, Heidelberg, Germany
We present a simple closed-form analytic expression for the probability of two-flavour neutrino oscillations in a matter with an arbitrary density profile. Our formula is based on a perturbative expansion and allows an easy calculation of higher order corrections. We demonstrate the validity of our results using a few model density profiles, including the PREM density profile of the Earth.
