| contents | Using the Schwinger proper time method I calculate exactly the bubble diagram contribution to the thermal neutrino self-energy, obtaining exact results that cannot be achieved using the contact approximation. These results allow me to obtain the dispersion relation for neutrino in a medium under several different conditions. |
