Calculating neutrino oscillation probabilities in matter

Neutrino oscillations have been a very hot research topic in particle physics. They provide a description to the Universe we live in and give a picture as to what it was in the past and what it is currently. Neutrino oscillations are a very effective tool in understanding the very fundamental questions like cp-violation. Since neutrinos pass through anything and everything without interacting, we have calculated neutrino oscillations in matter when neutrinos pass through the earth.
