Main Question or Discussion Point

Velocity of light changes when it passes through a material medium.

IS it possible for a particle(e. g. an electron) to travel faster than light in THAT medium? IF so, can someone give me some examples or experiments documenting this?

That is how we get cerenkov radiation - when a charge particle is moving faster than light in that medium.

If you google on this, or on AMANDA or ICE CUBE (both are experiments being done, of have been done, on Antartica to detect cosmic neutrinos), you should be able to read on the exact experiments using such concepts.
